Run the CONFIDENCE program for ten (10) replications with a con fi dence level of 90% (z = 1.65); keep the population mean of 50, standard deviation of 10, and sample sizes of 100.

a. How many of the con fi dence intervals contained the population mean? __________________

b. What percentage did you expect to contain the population mean? __________________

c. If you increased the number of replications, would you more closely approxi-mate the con fi dence level percent? Hint: Run CONFIDENCE and change the number of replications to observe what happens. YES _______ NO _________________

d. Why does increasing the number of replications not guarantee a more close approximation to the con fi dence level percent?
