6.Twenty year old men's weights have a population mean, of 155 pounds and a population standard deviation, of 22

pounds. Suppose that the distribution is right skewed. Suppose we take a random sample of 100 twenty year old men's

weights and compute the mean weight for the sample.

6C. Suppose the process of taking random sample size 100 is repeated many times and a histogram of the sample

means is created. Which statement best describes the shape of the histogram?

a. The histogram will be right skewed.

b. The histogram will be bell shaped and symmetrical.

c. The histogram will be bimodal.

d. Nothing can be concluded about the shape of the histogram.

6D.What is the standard deviation of the distribution that is described in question C?

a.22 pounds

b. 20.0 pounds

c. 2.2 pounds

d. Nothing can be concluded about the standard deviation.

6F.What is the probability that the mean weight for a sample will between 152.8 and 157.8 pounds?

a.0.0904

b. 0.9096

c. 0.7398

d. This cannot be determined because the original distribution is right skewed.
