The daily temperatures in fall and winter months in Virginia have a mean of 62°F. A meteorologist in southwest
Virginia believes the mean temperature is colder in this area. The meteorologist takes a random sample of 15 daily
temperatures from the fall and winter months over the last five years in southwest Virginia. The mean temperature
for the sample is 58°F with a standard deviation of 4.12°F. A significance test at an alpha level of a = 0.05 produces
a P-value of 0.001. What is the correct interpretation of the P-value?
There is a 0.1% chance that a sample mean temperature of at most 58°F will occur by chance if the true mean
temperature is 62°F.
Assuming the true mean temperature is 62°F, there is a 0.1% probability that the null hypothesis is true by chance
alone.
There is a 0.1% probability that a sample mean temperature of 58°F will occur by chance alone if the true mean
temperature is 62°F.
Assuming the true mean temperature is 62°F, there is a 99.9% probability that a sample mean of 58°F will occur
by chance alone.

In a recent poll, 510 people were asked if they liked dogs, and 62% said they did. Find the Margin of Error for this poll, at the 95% confidence level. Give your answer to four decimal places if possible.

Answers

Answer:

0.0421

Step-by-step explanation:

Given that

There are 510 people who asked they liked dogs

62% said that yes

We need to find out the margin of the error

So,

standard error is

= sqrt(0.62 × 0.38 ÷ 510)

= 0.0215

now the margin of error is

= 0.0215 × 1.96  z score

= 0.0421

The ratio of Luis´s salary and Andres´s salary is 5 to 3. In July by mistake, Andres received $720 more, which received the same amount from Luis. How much is Luis´s salary?

Answers

Answer:

Luis Salary is  1800 dollars

Step-by-step explanation:

Ration of Luis´s salary and Andres´s salary is 5:3

[tex]\frac{L}{A} = \frac{5}{3}\\3L -5A = 0[/tex] -- Eq (1)

Let Luis salary be X

Then Andrews salary in July would be A + 720 while Luis salary in July is L

L = A + 720  ---E q (2)

Substituting the values in above equation 1, we get -

[tex]3 ( A +720 ) -5A = 0\\2 A = 720 *3\\A = 1080[/tex]

Luis Salary is

[tex]A + 720 = 1800[/tex]

A standard die is rolled three times. What is the probability of rolling a number less than 5 on all three rolls?

Answers

Answer:

5/6

Step-by-step explanation:

This is because when you roll three times, there are 18 possible numbers (six numbers three times). If you want to get less than five each time, that is 5 number x 3 rolls = 15 numbers.

So...You get 15/18 which simplifies to 5/6

According to these measures, is it possible that the heaviest piece of fruit in the two samples was an orange? Explain why or why not.

Answers

Answer:

Yes,

Step-by-step explanation:

The measures given which are median and interquartile range have no effect on what the maximum value of a certain distribution will be.

In essence, the information given about the samples of fruits and apples do not point to which fruit sample should possess the sample with maximum weight as the information only gives a general description of each distribution. This means that either samples of orange or apple could have the heaviest piece of fruit.

Decide which ONE of the following statements is FALSE.

A) A line contains at least two points
B) Three non-colinear points determine a plane
C) Through any two distinct points there exists exactly one line
D) Any three points lie on a distinct line

Answers

True or False.

A is true, a line has two points which are the two ends.

Answer: Choice D

Any three points lie on a distinct line

=============================================================

Explanation:

Let's go through each statement to see which are true, and which are false.

A) True. A line is uniquely defined by two points. In other words, you need 2 points to form a line.B) True. A plane is a flat surface, such as a table top or a piece of paper. The paper is not allowed to bend or curve. The three points cannot all fall on the same line, hence the "non-colinear" condition put in there. If the 3 points were colinear, then infinitely many planes would go through those points. So we make them non-colinear so a unique single plane can be defined. C) True. See choice A above.D) False. While two points form a single line, that third point may or may not be on that line. If the three points form a single line, then we consider the points colinear. If the points don't all fall on the same line, then we say they are non-colinear. For non-colinear points, a triangle forms. If choice D said "any three colinear points lie on a distinct line", then that statement would be true.

Side note: The spelling of "colinear" is sometimes "collinear" with two "L"s, instead of one. I'm not 100% sure which spelling is more acceptable. I've found sources that have used both.

Answers

Answer:

76017.69 mm²

631000 mm³

295045.04 mm³

Step-by-step explanation:

Surface area = bh + 2ls + lb

Since the sides of the triangular prism are equal (equilateral triangle) = 60 mm each

Height = 405 mm

The surface area of triangular = 76017.69 mm

The volume of triangular prism :

1/2 * base * height * length

Volume = 631000 mm³

If amount of chocolate inside = 335954.96 mm3

Empty space =

Volume of triangular prism - amount of chocolate inside

631000 - 335954.96

= 295045.04 mm³
