The sampling distribution in this case is positively skewed. This is due to the fact that the mean is greater than the median, and the data is spread out further to the right than to the left, resulting in a long right tail on the histogram.

What is data?

Data is information that has been collected, organized, and presented in a meaningful way. It can include facts, figures, observations, and other information, such as survey responses, images, and videos. Data is used to inform decision-making, inform research and analysis, and generate insights. Data can be qualitative or quantitative, and it is often gathered from multiple sources. Data can be collected through surveys, experiments, observational studies, or other methods. When combined with analytical tools, data can be used to identify patterns and trends, generate insights, and develop strategies.

The best description of the shape of the sampling distribution in this case would be positively skewed. Positively skewed distributions occur when the mean is greater than the median, and the data is spread out further to the right than to the left. This results in a long tail on the right side of the histogram that skews the data in a positive direction. To determine if this is the case, we can calculate the mean and median of the data.

To calculate the mean, we will use the formula for the population mean: $$\mu = \frac {\sum_{i=1}^n x_i} n$$

where $\mu$ is the population mean, $\sum_{i=1}^n$ represents the sum of all the data points, and $n$ is the sample size.

For the median, we can use the formula for the population median: $$Median = \frac{n+1}{2}th \ \ term$$

where $n$ is the sample size.

In this case, the sample size is 36, so the median would be the 18.5th term.

Now that we have the formulas, we can calculate the mean and median of the data.

The mean of the data is $46,408.89$.

The median of the data is $25,000.

Since the mean is greater than the median, it indicates that the data is positively skewed. This is further confirmed by examining the histogram of the data, which shows a long right tail on the right side of the histogram.

What exactly is a circle? How do we use circles to reason about distance without using a ruler?​

Answers

A circle is a closed curve with all points equidistant from a fixed point called the center, characterized by a radius and diameter.

A circle is a two-dimensional geometric shape consisting of all points in a plane that are equidistant from a fixed point called the center. In other words, a circle is a closed curve that forms a perfect, continuous loop, where every point on the curve is the same distance from the center.

The distance between the center of the circle and any point on the curve is called the radius, which is denoted by the letter 'r'. The diameter of a circle is the distance across the circle passing through the center and is twice the length of the radius.

Circles have many important properties and are fundamental to many areas of mathematics, science, and engineering. They are often used in geometry to model real-world phenomena and are used in a wide range of applications, from constructing wheels to designing satellites.

Find the volume of the rectangular prism.
9 yd
Pyd
4 yd

Answers

Answer:

To find the volume of a rectangular prism, we need to multiply its length, width, and height.

The given dimensions are:

Length = 9 yd

Width = Pyd (it's unclear what this means, so let's assume it's a typo and the intended value is 3 yd or 4 yd)

Height = 4 yd

Assuming the width is 3 yd, the volume of the rectangular prism is:

Volume = Length x Width x Height

Volume = 9 yd x 3 yd x 4 yd

Volume = 108 cubic yards

Assuming the width is 4 yd, the volume of the rectangular prism is

Volume = Length x Width x Height

Volume = 9 yd x 4 yd x 4 yd

Volume = 144 cubic yards

Therefore, the volume of the rectangular prism is either 108 cubic yards or 144 cubic yards, depending on the intended value of the width.

What is a repeated measures ANOVA ?

A repeated measures ANOVA is a statistical test used to analyze data from experiments in which the same participants are measured multiple times under different conditions. This design is sometimes referred to as a "within-subjects design" because each participant is measured within the same group.

Here are the steps for conducting a repeated measures ANOVA:

State the null and alternative hypotheses.Check the assumptions of the test, which include normality, sphericity, and homogeneity of variance.Calculate the within-subjects sum of squares (SSW), the between-subjects sum of squares (SSB), and the total sum of squares (SST).Calculate the degrees of freedom (df) for each of these sums of squares.Calculate the mean square (MS) for each source of variance by dividing the sum of squares by the degrees of freedom.Calculate the F ratio by dividing the between-subjects MS by the within-subjects MS.Determine the critical value for the F ratio using a table or software.Compare the calculated F ratio to the critical value. If the calculated F ratio is greater than the critical value, reject the null hypothesis and conclude that there is a significant effect of the independent variable on the dependent variable.If the null hypothesis is rejected, follow up with post hoc tests to determine which conditions differ significantly from each other.

Answers

Answer:

40 ft

Step-by-step explanation:

the starting point is like the origin on the coordinate grid.

let's say forward for your friends is the positive y direction, and right for your friend is positive x direction.

the end point coordinates of your friend are then

(15, 20)

forward for you (facing in the other direction) is the the negative y direction. and going right for you is then actually going in the negative x direction.

your end point is therefore

(-9, -12)

the distance between both points is then per Pythagoras (and the derived distance formula) :

distance² = (x1 - x2)² + (y1 - y2)² =

= (15 - -9)² + (20 - -12)² = 24² + 32² =

= 576 + 1024 = 1600

a -foot-long footbridge has two diagonal supports that meet in the center of the bridge. each support makes a angle with a short vertical support. a diagram shows the footbridge, the diagonal supports and the vertical supports create two right triangles. at the top of the diagram a horizontal line is shown and labeled 20 feet. the two right triangles are shown below this horizontal line.the two longest legs of both right triangles touch at the center of the footbridge.the shortest leg of both right triangles represents the vertical support on each end of the footbridge. the hypotenuse of both right triangles form the diagonal supports that meet at the center of the footbridge. the full length of the footbridge is 20 feet. the vertical supports are not labeled. each diagonal support is labeled x. a 65-degree-angle is formed between the short vertical support and the diagonal support on each end of the bridge. what is the length x of a diagonal support, to the nearest tenth of a foot?

Answers

The length of a diagonal support (x) is approximately 18.4 feet to the nearest tenth of a foot.

To find the length x of a diagonal support, we will use the information given about the right triangles formed by the vertical supports, diagonal supports, and the horizontal line (representing half the length of the footbridge).
Since the full length of the footbridge is 20 feet, the horizontal line in each right triangle measures half of that, which is 10 feet.
The angle formed between the short vertical support and the diagonal support is given as 65 degrees.
We'll use the sine function to find the length x of the diagonal support.

In this case, sine(65) = opposite side (vertical support) / hypotenuse (diagonal support or x).
We first need to find the length of the vertical support.

To do this, we can use the tangent function.

In this case, tangent(65) = opposite side (vertical support) / adjacent side (10 feet).
Solving for the vertical support: vertical support = 10 * tangent(65) ≈ 17.1 feet.
Now, we can plug this value back into the sine equation: sine(65) = 17.1 / x.
Solving for x (the diagonal support): x = 17.1 / sine(65) ≈ 18.4 feet.

Answers

7.071 is the length, in inches, of each side of the square.

What is meant by "square"?

The term "square" refers to a regular quadrilateral having four equal-length sides and angles. Angles in the square are at right angles or are separated by 90 degrees. The diagonals of the square are also equal and meet at a 90-degree angle.

                             Having equal length sides and right angles on all four, a square is a quadrilateral. Due to the fact that a square's sides are all the same length, it may be distinguished from other types of rectangles. Every square consequently becomes a rectangle since it is a quadrilateral with right angles at all four of its angles.

If the side od=f a square is s, the diagonal is  s√2

  This comes from Pythagoras as diagonal is

   √s² + s²  = √2s² = s√2

 as such s√2 = 10

           s = 10/√2

        = 10 * √2/√2  * √2

The​ life, in​ years, of a certain type of electrical switch has an exponential distribution with an average life betaequals3. If 300 of these switches are installed in different​ systems, what is the probability that at most 70 fail during the first​ year?

Answers

The probability that at most 70 switches fail during the first year is low, at around 1.3%.

The problem involves the use of the exponential distribution to model the lifetime of a certain type of electrical switch. Specifically, we are given that the average life of these switches is beta = 3.

The exponential distribution is often used to model the time between occurrences of a certain event, such as the failure of a component. In this case, we can use it to model the time between failures of the electrical switches.

To answer the question, we need to find the probability that at most 70 switches fail during the first year. Let X be the number of switches that fail during the first year. We know that X follows a Poisson distribution with parameter lambda = (1/3)*300 = 100.

This is because the expected number of failures per year for each switch is 1/3 (since the average life is 3 years), and there are 300 switches installed.

Therefore, we can use the Poisson distribution to calculate the probability that at most 70 switches fail during the first year:

P(X <= 70) = e^(-100) * (100^0/0!) + e^(-100) * (100^1/1!) + ... + e^(-100) * (100^70/70!)

This can be calculated using a calculator or software such as Excel. The answer is approximately 0.013, or 1.3%. This suggests that the switches are fairly reliable, and that it is unlikely that a large number of them will fail in a short period of time.

5 (-x-1)=x+21 - 6xn what is the solution to the following equation

Answers

To solve the equation 5(-x-1) = x+21 - 6xn, we can start by simplifying both sides of the equation:

5(-x-1) = x+21 - 6xn

-5x - 5 = x + 21 - 6xn

Next, we can gather all the x terms on one side and all the constant terms on the other side:

-5x - x + 6xn = 21 + 5

-6x + 6xn = 26

Factor out x on the left side:

x(-6 + 6n) = 26

Then divide both sides by (-6 + 6n):

x = 26 / (-6 + 6n)

This is the solution to the equation. However, we need to consider one special case: if (-6 + 6n) equals zero, then the denominator is zero, which makes the solution undefined. Therefore, the solution is valid only if (-6 + 6n) is not equal to zero.

In summary, the solution to the equation 5(-x-1) = x+21 - 6xn is x = 26 / (-6 + 6n), where n is any number except n = 1.

Noah is visiting his aunt in Texas. He wants to buy a belt buckle whose price is $25. He knows that the sales tax in Texas is 6.25%.
How much will the tax be on the belt buckle?

Answers

The tax on the belt buckle is $1.56

What is Rate?

In general terms, a rate is a measure of the relationship between two quantities that are measured in different units. A rate expresses how much of one thing there is per unit of another thing. For example, miles per hour is a rate that expresses how many miles are traveled in one hour.

To calculate the tax on the belt buckle, we need to multiply the price of the belt buckle by the sales tax rate:

Tax = Price x Tax rate

In this case, the price of the belt buckle is $25 and the sales tax rate is 6.25%. To convert the tax rate from a percentage to a decimal, we need to divide it by 100:

Tax rate = 6.25% ÷ 100 = 0.0625

Now we can calculate the tax on the belt buckle:

Tax = Price x Tax rate

= $25 x 0.0625

= $1.56

Therefore, the tax on the belt buckle is $1.56. The total cost of the belt buckle including tax would be $25 + $1.56 = $26.56.

Answers

If some students checked 6 bags of Doritos marked with a "net-weight" of 28.3 grams, then these data satisfies all the three assumptions for inference (random condition, independent condition and normal condition.

To determine whether weight of bag satisfy the assumptions for inference, we need to consider the assumptions of statistical inference.

The assumptions are :

(i) Random Sampling: The data should be collected from a random sample, where each bag of Doritos has an equal chance of being selected.

This assumption is satisfied, because we assume that the "6-bags" are randomly selected.

(ii) Independence: The data points should be independent of each other, meaning that the weight of one bag of Doritos should not depend on the weight of another bag.

This assumption is satisfied as, bags were weighed separately and their weights were recorded without any influence from other bags.

(iii) Normality: The distribution of the data should be approximately normal.

This assumption is also satisfied , because histogram shows that there are "No-Outliers" and normal "quantile-plot" is linear.

The percentage of all scores that occur at 36 or above is approximately 15.87% if the mean of the distribution is 20 and standard deviation is 6.

We can use the Z-score formula to standardize the value of 36 and find the corresponding area under the normal curve.

The Z-score for a score of 36 in this distribution is

Z = (X - μ) / σ

Z = (36 - 30) / 6

Z = 1

Using a standard normal table or calculator, we can find the area under the normal curve to the right of Z = 1

Answer:

x ≈ 48.6°

Step-by-step explanation:

using the sine ratio in the right triangle

sin x = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{21}{28}[/tex] = [tex]\frac{3}{4}[/tex] , then

x = [tex]sin^{-1}[/tex] ( [tex]\frac{3}{4}[/tex] ) ≈ 48.6° ( to the nearest tenth )

an instructor was interested in seeing if there was a difference in the average amount of time that men and women anticipate studying for an introduction to statistics course in the summer. a group of men and women were randomly selected from the university of florida. the minitab results are below. what is the best interpretation of the results below?

Answers

The best interpretation of the results would depend on the specific statistical analysis used and the results obtained.

The results indicated a statistically significant difference between the mean anticipated study times for men and women, the interpretation would be that men and women have different average anticipated study times for the introduction to statistics course.

Conversely, if there was no statistically significant difference, the interpretation would be that there is no evidence to suggest that men and women have different average anticipated study times for the course.

As the Minitab results are not provided in the question, I cannot interpret them.

Provide a general interpretation of the statistical analysis based on the information given.

The instructor was interested in seeing if there was a difference in the average amount of time that men and women anticipated studying for an introduction to statistics course in the summer.

To test this hypothesis, a group of men and women were randomly selected from the University of Florida.

The statistical analysis may have involved using a t-test or a similar method to compare the mean anticipated study times between men and women.

The results of this analysis would provide information on whether there is a statistically significant difference between the mean anticipated study times for men and women.

a room has a wall with an r-value of 15 f sq.ft. hr/btu. the room is 13 feet long and 11 feet wide with walls that are 9 ft high. on a particular day the average outside temperature is 36 degrees f. how much heat is transferred through the walls on that day (in btus)? answer to two decimal places without a unit.

Answers

On that particular day, approximately 272.32 BTUs of heat were transferred through the wall.

To calculate the amount of heat transferred through the walls on a particular day, we can use the formula:

Q = U × A × deltaT

where Q is the heat transferred (in BTUs), U is the overall heat transfer coefficient (in BTU/hr·ft^2·°F), A is the area of the wall (in ft^2), and deltaT is the temperature difference between the inside and outside of the wall (in °F).

First, let's calculate the area of the wall. The room has four walls, but we are only interested in the heat transferred through the wall with an R-value of 15. We can calculate the area of this wall as follows:

Area = Length × Height = 13 ft × 9 ft = 117 ft^2

Next, we need to calculate the overall heat transfer coefficient, U. The U-value is the reciprocal of the R-value, so:

U = 1 / R = 1 / 15 = 0.0667 BTU/hr·ft^2·°F

Now we need to calculate the temperature difference between the inside and outside of the wall. We are given that the outside temperature is 36 °F, but we don't know the inside temperature. Let's assume that the inside temperature is 70 °F, which is a typical room temperature. Then the temperature difference is:

deltaT = 70 °F - 36 °F = 34 °F

Finally, we can plug these values into the formula:

Q = U × A × deltaT

Q = 0.0667 BTU/hr·ft^2·°F × 117 ft^2 × 34 °F

Q ≈ 272.32 BTUs

Therefore, on that particular day, approximately 272.32 BTUs of heat were transferred through the wall.

You have a TV that is 30 inches tall and 40 inches wide. What is the length of the diagonal of the TV. (The measure from bottom left to top right of the TV)

2500 inches


1250 inches


50 inches


26.5 inches

Answers

Answer:

50 inches

Step-by-step explanation:

Using the Pythagorean theorem, we can find the length of the diagonal of the TV:

diagonal^2 = height^2 + width^2

diagonal^2 = 30^2 + 40^2

diagonal^2 = 900 + 1600

diagonal^2 = 2500

Taking the square root of both sides, we get:

diagonal = sqrt(2500)

diagonal = 50

Therefore, the length of the diagonal of the TV is 50 inches.

diagonal^2 = height^2 + width^2
diagonal^2 = 30^2 + 40^2
diagonal^2 = 900 + 1600
diagonal^2 = 2500
Taking the square root of both sides, we get:
diagonal = sqrt (2500)
diagonal = 50
