In Exercises 110-140, use the population of{2, 3, 5, 9} of the lengths of hospital stay(days) of mothers who gave birth, foundfrom Data Set 6 "Births" in Appendix B.Assume that random samples of size n = 2are selected with replacement.11. SAMPLING DISTRIBUTION OFTHE SAMPLE MEANa. After identifying the 16 differentpossible samples, find the meanof each sample, and then con-struct a table representing thesampling distribution of the sam-ple mean. In the table, combinevalues of the sample mean thatare the same. (Hint: See Table 6-3 in Example 20.)b. Compare the mean of the popu-lation {2, 3, 5, 9} to the mean ofthe sampling distribution of thesample mean.c. Do the sample means target thevalue of the population mean? Ingeneral, do sample means makegood estimators of populationmeans? Why or why not?

The population is given as: 2, 3, 5, 9. Thus the population size, N=4 A sample size 2 (i.e., n=2) is…
