A sample is chosen randomly from a population that was strongly skewed to the left. a) Describe the sampling distribution model
Nana76 [90]

Answer:

a. The sampling distribution for the sample mean will be skewed to the left centered at the average u, and standard deviation will be  ∅/\sqrt{n}

b. The sample distribution will be normal in shape and will be centered at the average u, . standard deviation will be ∅/\sqrt{n}1

c. As the size of the sample increases, the sample distribution should draw near  and resemble the distribution of the population

Step-by-step explanation:

A sample is chosen randomly from a population that was strongly skewed to the left. a) Describe the sampling distribution model for the sample mean if the sample size is small. b) If we make the sample larger, what happens to the sampling distribution model’s shape, center, and spread? c) As we make the sample larger, what happens to the expected distribution of the data in the sample?

The following answers will march the questions above:

a. The sampling distribution for the sample mean will be skewed to the left centered at the average u, and standard deviation will be  ∅/\sqrt{n}

b. The sample distribution will be normal in shape and will be centered at the average u, . standard deviation will be ∅/\sqrt{n}1

c. As the size of the sample increases, the sample distribution should draw near  and resemble the distribution of the population

The current temperature in Smalltown is 20 degrees F. This is 6 degrees less that twice the temperature that it was 6 hours ago.
IRISSAK [1]

The temperature was 13 degrees Fahrenheit in Small town six hours ago.

Step-by-step explanation:

Given,

Current temperature in Small town = 20 degrees Fahrenheit

Let,

x be the temperature 6 hours ago.

According to given statement;

This is 6 degrees less that twice the temperature that it was 6 hours ago.

20 = 2x - 6\\ 20+6=2x\\26=2x\\2x=26

Dividing both sides by 2

\frac{2x}{2}=\frac{26}{2}\\x=13

The temperature was 13 degrees Fahrenheit in Small town six hours ago.
