# Question

For the distribution of the sample means that you produced in Exercise 7 (truck odometers),

a. Show that the mean of the distribution is equal to the population mean.

b. Compute the standard deviation of the distribution directly from the table or bar chart that describes the distribution.

c. Show that the standard deviation you computed in

(The fpc is needed here because the sample size is more than 5% of the population size.)
