in the chi square test for independence, the null hypothesis and the research hypothesis select one: a. always contradict each other b. always agree with each other c. are never actually stated d. are usually both rejected
In "Chi-Square-test" for the inde-pendence, "re-search-hypothesis" and "null-hypothesis" always contradict each other, the Option(a) is correct.
In the "Chi-Square" test for independence, the "Null-Hypothesis" (H₀) assumes that there is no association between the two categorical variables being tested, while the research hypothesis (Hₐ) proposes that there is a significant association between the variables.
These hypotheses are mutually exclusive and contradictory to each other.
If the "null-hypothesis" is rejected based on the results of the chi-square test, it implies that there is evidence to support the "research-hypothesis", which indicates that there is a significant association between the variables.
Conversely, if "null-hypothesis" is not rejected, it suggests that there is not enough evidence to support the "research-hypothesis", and the conclusion would be that there is no significant association between the variables.
Therefore, the correct option is (a).

The table shows the results of a recent survey of sixth grade students at Potter Middle School about their favorite sports.
What fraction of the students chose football or soccer? Express your answer in simplest form.
20% of the students surveyed did not choose soccer, football, or basketball as their favorite sport.
To find the percentage of students who did not choose soccer, football, or basketball as their favorite sport, we need to first find the total number of students who did not choose any of these sports.
Total number of students who chose soccer, football or basketball = 54 + 42 + 24 = 120
Number of students who did not choose any of these sports = 150 - 120 = 30
Therefore, the percentage of students who did not choose soccer, football or basketball as their favorite sport is:
(30/150) x 100% = 20%
So, 20% of the students surveyed did not choose soccer, football, or basketball as their favorite sport.

the dimensions of noah’s ark were reported as 3.0 × 102 cubits by 5.0 × 101 cubits. express this size in units of feet (1 cubit = 1.5 ft)
The dimensions of Noah's Ark in feet are 450 feet by 75 feet if the dimensions of Noah's Ark is 3.0 × 102 cubits by 5.0 × 101 cubits.
Noah's Ark is said to have dimensions of 3.0 × 10^2 cubits by 5.0 × 10^1 cubits. To convert these measurements to feet, we can use the conversion factor of 1 cubit = 1.5 feet.
First, we need to convert the length of the ark from cubits to feet. To do this, we multiply the length of the ark in cubits (3.0 × 10^2) by the conversion factor of 1.5 feet/cubit. This gives us a length of
3.0 × 10^2 cubits x 1.5 feet/cubit = 450 feet
Similarly, we can convert the width of the ark from cubits to feet by multiplying the width in cubits (5.0 × 10^1) by the conversion factor of 1.5 feet/cubit. This gives us a width of:

assume that arrivals occur according to a poisson process with an average of seven per hour. what is the probability that exactly two customers arrive in the two-hour period of time between a 2:00 p.m. and 4:00 p.m. (one continuous two-hour period)? b 1:00 p.m. and 2:00 p.m. or between 3:00 p.m. and 4:00 p.m. (two separate one-hour periods that total two hours)?
a) The probability that exactly two customers arrive between 2:00 p.m. and 4:00 p.m. is 0.0915 (or approximately 9.15%).
b) The probability of at least one customer arriving between 1:00 p.m. and 2:00 p.m. or between 3:00 p.m. and 4:00 p.m. is approximately 0.99999917.
For a Poisson process, the number of arrivals in a fixed time interval follows a Poisson distribution.
Let's denote the number of arrivals in a two-hour period as X.
Since the average number of arrivals per hour is 7, the average number of arrivals in a two-hour period is 14.
Therefore, we have λ = 14.
a) Probability of exactly 2 customers arriving between 2:00 p.m. and 4:00 p.m.:
Using the Poisson distribution formula, the probability of X arrivals in a two-hour period is:
[tex]P(X = x) = (e^{-\lambda} * \lambda^x) / x![/tex]
So, for X = 2, we have:
[tex]P(X = 2) = (e^{-14} * 14^2) / 2! = 0.0915[/tex] (rounded to four decimal places)
Therefore, the probability that exactly two customers arrive between 2:00 p.m. and 4:00 p.m. is 0.0915 (or approximately 9.15%).
b) Probability of at least one customer arriving between 1:00 p.m. and 2:00 p.m. or between 3:00 p.m. and 4:00 p.m.:
We can approach this problem by using the complementary probability. The complementary probability of at least one customer arriving in a two-hour period is the probability of no customers arriving in that period. Since the arrival rate is the same for each hour, we can divide the two-hour period into two one-hour periods and use the Poisson distribution formula for each period separately.
The probability of no customers arriving in a one-hour period with λ = 7 is:
[tex]P(X = 0) = (e^{-7}* 7^0) / 0! = 0.000911[/tex]
The probability of no customers arriving in a two-hour period is the product of the probabilities for each one-hour period:
P(no customers in two-hour period) = P(X = 0) * P(X = 0) = 0.000911 * 0.000911 = 8.30e-7
The complementary probability of at least one customer arriving in a two-hour period is:
P(at least one customer in two-hour period) = 1 - P(no customers in two-hour period) = 1 - 8.30e-7 = 0.99999917 (rounded to eight decimal places).

the dimensions of a square right pyramid are shown below. the pyramid is sliced by a plane that passes vertically through the top vertex and is perpendicular to the base. what is the resulting two-dimensional shape and the area of the plane section?
The resulting two-dimensional shape is a square with an area of 72 square units.
The pyramid is a square right pyramid, the base is a square and the vertical height meets the base at its center. When the pyramid is sliced by a plane that passes vertically through the top vertex and is perpendicular to the base, the resulting two-dimensional shape is a square.
The plane section intersects the four triangular faces of the pyramid, creating four smaller triangles with the same shape and size. These four triangles can be rearranged to form a smaller square that is similar to the larger square base of the pyramid. The area of the plane section is equal to the area of the smaller square, which is proportional to the area of the larger square base. The proportionality constant is equal to the ratio of the height of the plane section to the height of the pyramid.
Let H be the height of the pyramid and h be the height of the plane section. Then, we have:
h/H = (side length of smaller square)/(side length of larger square)
= √(2)/2
Solving for h, we get:
h = (√(2)/2) * H
The area of the plane section is then:
A = (side length of smaller square)²
= (√2)/2 * side length of larger square)²
= (√(2)/2)² * (side length of larger square)²
= (1/2) * (side length of larger square)²
Since the side length of the larger square base is given, we can substitute it in and simplify to get:
A = (1/2) * (12)² = 72 square units
As a result, the resultant two-dimensional form is a square with 72 square units of area.

First, I am going to put the numbers in order from least to greatest. This will help us in finding the median and mode, but also can be easier to see if the mean we find makes sense.
➜ 1 2 2 2 2 2 3 3 4 5 5 6 6 7 8 8 9 9 10 11
Mean is the average of all of the numbers. We will add all the numbers together and then divide by the number of numbers.
1+2+2+2+2+2+3+3+4+5+5+6+6+7+8+8+9+9+10+11 = 105
105 / 20 = 5.25
Median is the middle number, when in order from least to greatest.

Mary worked from Monday to Saturday last week and bought lunch in the company’s restaurant every day. Her lunches cost a different amount every day. Each lunch cost a multiple of 20¢. The most expensive lunch of the week cost $7. 60 and the cheapest one cost $4. 40. Friday’s lunch cost exactly 1½ times as much as Wednesday’s lunch. Tuesday’s lunch cost $1. 20 more than Thursday’s lunch
The minimum total cost of Mary's six lunches is $30.40.
To approach this problem, we need to consider the cost of each lunch individually and then sum them up to get the total cost. Let's start by finding the cost of Wednesday's lunch. We know that Friday's lunch cost 1.5 times as much as Wednesday's lunch, so we can write:
Friday's lunch = 1.5 x Wednesday's lunch
We also know that each lunch costs a multiple of 20 cents, so we can write:
Friday's lunch = $x, where x is a multiple of 20 cents
Wednesday's lunch = $y, where y is a multiple of 20 cents
Combining these two equations, we get:
$x = 1.5y
Since we're looking for the minimum total cost, we want to minimize the cost of each lunch. The cheapest lunch costs $4.40, which is equivalent to 22 multiples of 20 cents. So we can write:
$4.40 ≤ y ≤ $7.60
Now, we can use the information about Tuesday's lunch to find the cost of Thursday's lunch. We know that Tuesday's lunch cost $1.20 more than Thursday's lunch, so we can write:
Tuesday's lunch = Thursday's lunch + $1.20
Again, each lunch costs a multiple of 20 cents, so we can write:
Tuesday's lunch = $z, where z is a multiple of 20 cents
Thursday's lunch = $w, where w is a multiple of 20 cents
Combining these two equations, we get:
$z = w + $1.20
Now, we have two equations and two unknowns (x and y) and (z and w). We can solve these equations simultaneously to find the cost of each lunch. We get:
x = 1.5y
z = w + $1.20
We can substitute the first equation into the second equation to get:
z = 1.5y + $1.20
Now we have three equations and three unknowns (x, y, and z). We also know that each lunch costs a multiple of 20 cents, so we can write:
x = $a, where a is a multiple of 20 cents
y = $b, where b is a multiple of 20 cents
z = $c, where c is a multiple of 20 cents
Substituting these values into our equations, we get:
$a = 1.5b
$c = b + $1.20
$4.40 ≤ b ≤ $7.60
We can solve for b by substituting the second equation into the third equation:
$c = b + $1.20
$b = c - $1.20
Substituting this value of b into the first equation, we get:
$a = 1.5(c - $1.20)
$a = 1.5c - $1.80
Now, we can substitute these values into our equation for the total cost of Mary's six lunches:
Total cost = $a + $b + $c + $d + $e + $f
Total cost = $1.5c - $1.80 + $c + $b + $b + $c + $d + $e
Total cost = $4c - $1.80 + $b + $d + $e
We want to minimize the total cost, so we want to minimize each term in the above equation. We know that the minimum value of b is $4.40, and we want to choose c, d, and e to be as close to $4.40 as possible. This will minimize the total cost. The maximum value of c is $7.60, so we can choose c to be $7.60. We can then choose d and e to be $4.40 each, since these are the minimum possible values.
Substituting these values into our equation for the total cost, we get:
Total cost = $4c - $1.80 + $b + $d + $e
Total cost = $4($7.60) - $1.80 + $4.40 + $4.40
Total cost = $30.40

We can find the sum of the interior angles of any polygon using the formula
[tex]S_{n}=180(n-2)[/tex], where n is the number of sides.
Because each of these polygons have four sides, we can use one formula where our n is 4 to find the sum of the interior angles:
[tex]S_{4}=180(4-2)\\ S_{4}=180*2\\ S_{4}=360[/tex]
Thus, for all four problems, we can set the four angles equal in the four polygons equal to 360 and solve for the variables
(15) *Note the right angle symbol in this problem which always equals 90°
[tex]84+90+(2x+118)+(2x+68)=360\\174+2x+118+2x+68=360\\360+4x=360\\4x=0\\x=0[/tex]
Now, to find the measure of <Y, we simply plug in 0 for x in its equation
m<Y = 2(0) + 118 = 118°
(16):
[tex]82+105+(8x+11)+10x=360\\187+8x+11+10x=360\\198+18x=360\\18x=162\\x=9[/tex]
To find the measure of <F, we plug in 9 for x in its equation
m<F = 10(9) = 90°
(17):
[tex]95+95+(10x-5)+(8x+13)=360\\190+10x-5+8x+13=360\\198+18x=360\\18x=162\\x=9[/tex]
To find the measure of <M, we plug in 9 for x in its equation
m<M = 10(9) - 5 = 85°
(18):
[tex](14x-7)+(11x-2)+93+76=360\\14x-7+11x-2+169=360\\25x+160=360\\25x=200\\x=8[/tex]
To find the measure of <M, we plug in 8 for x in its equation

This technique involves selecting a sample from the population in such a way that every member of the population has an equal chance of being included in the sample.
In this case, the population of interest is all the psychology major students in the university.
The department head wants to understand their attitudes toward implementing an internship as a requirement for completing their degree.
To obtain a representative sample, she first compiles a list of all psychology majors.
Then, she randomly selects 100 students from this list to participate in her survey.
Simple random sampling is an effective method to ensure that the sample is unbiased and representative of the entire population.
It minimizes selection bias, as each student has an equal chance of being selected.
This allows the department head to generalize her findings and make valid inferences about the attitudes of all psychology students in the university.
To summarize, the department head employed a simple random sampling technique to gather information about students' attitudes towards implementing an internship as a requirement for completing their psychology degree.
This approach helps ensure the sample is representative and unbiased, allowing for accurate and generalizable conclusions.

shawna is going out of town for the day, so she asks a friend to watch her 3 dogs. she wants to leave 12 of a pound of food for each dog. if a can of dog food has 0.75 pounds of food, how many cans should shawna leave?write your answer as a whole number, decimal, fraction, or mixed number. simplify any fractions.
Shawna wants to make sure her three dogs are fed and cared for when she leaves town for the day. She intends to give each of her dogs 12 ounces of food to achieve this. She must therefore leave a total of 36 ounces of food (3 dogs x 12 ounces of food per dog). 36 ounces are equivalent to 2.25 pounds of food because 16 ounces make up one pound.
There are 0.75 pounds of food in each can of dog food. We must divide 2.25 by 0.75 to find the quantity of dog food Shawna should leave for her companion. 3 dog food cans are the end outcome.Shawna ought to give her buddy three cans of dog food so that she can feed her dogs.
Shawna may make sure her dogs have enough food and are well cared for while she is away by leaving adequate food for them. Shawna may put any fears or concerns about her pets' welfare to rest by leaving ample food and clear directions.

The interval within which 95 percent of all possible sample estimates will fall by chance is defined as ______________.A. Lower confidence boundaryB. Upper confidence boundaryC. The sample mean +/- 1.96 standard errorsD. The Central Limit Theorem
The interval within which 95 percent of all possible sample estimates will fall by chance is defined as the sample mean +/- 1.96 standard errors.
C. The sample mean +/- 1.96 standard errors.
This is known as the confidence interval, and it is calculated by taking the sample mean and adding and subtracting 1.96 times the standard error of the sample.
This range provides a level of confidence that the true population parameter falls within this range, based on the sample data.
The Central Limit Theorem is a statistical concept that explains how sample means tend to follow a normal distribution, but it is not directly related to the calculation of confidence intervals.
The lower and upper confidence boundaries refer to the endpoints of the confidence interval.
