Repeat Exercise 11 using variances instead of means.

Data from in Exercise 11

a. After identifying the 16 different possible samples, find the mean of each sample, then construct a table representing the sampling distribution of the sample mean. In the table, combine values of the sample mean that are the same.
b. Compare the mean of the population 534, 36, 41, 516 to the mean of the sampling distribution of the sample mean.
c. Do the sample means target the value of the population mean? In general, do sample means make good estimators of population means? Why or why not?

In use the population of {34, 36, 41, 51} of the amounts of caffeine (mg , random samples of size n = 2 are selected with replacement.
