Run the CONFIDENCE program for fi fty (50) 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. Do all the con fi dence intervals have the same width? YES ________ NO _________________

b. What is the width of the con fi dence interval? _________________________

c. Compute the con fi dence interval width using the population standard devia-tion and the sample size formula in the chapter.

d. Does the formula give the same con fi dence interval width as the CONFIDENCE program?
