I am having issues figuring out question a and f. I have added in the correct answers to the other questions that were asked for your convenience.

Scrapper Elevator Company has 20 sales representatives who sell its product throughout the United States and Canada. The number of units sold last month by each representative is listed below. Assume these sales figures to be the population values.

2 3 2 3 3 4 2 4 3 2 2 7 3 4 5 3 3 3 3 5

**a.Draw a graph showing the population distribution. (units sold x-axis/ frequency y-axis)

b.Compute the population mean.Answer= 3.3

c.Compute the standard deviation. Answer= 1.23

d. If you were able to list all possible samples of size five from this population of 20, how would the sample means be distributed? Answer=The central limit theorem says that the sample means would tend to be normally distributed.

e.What would be the mean of the sample means? Answer=3.30

**f. What would be the standard deviation of the sample means?(The answer is NOT .28)
