In Exercises 1114, use the population of ages {56, 49, 58, 46} of the four U.S. presidents (Lincoln, Garfield, McKinley, Kennedy) when they were assassinated in office. Assume that random samples of size n = 2 are selected with replacement.. Sampling Distribution of the Sample Meana. After identifying the 16 different possible samples, find the mean of each sample, then construct a table representing the sampling distribution of thesample mean. In the table, combine values of the sample mean that are the same. (Hint: See Table 64 in Example 1.)b. Compare the mean of the population {56, 49, 58, 46} 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 orwhy not?
