Suppose that sample is drawn and z (?/2) = 1.96 and ? = 20. Answer the following questions:
(A) If the Maximum Error of Determine is 0.04 for this sample, what would be the sample size?
(B) Given that the sample Size is 400 with this same z (?/2) and ?, what would be the Maximum Error of Estimate?
(C) What happens to the Maximum Error of Estimate as the sample size gets smaller?
(C) What effect does the answer to C above have to the size of the confidence interval?
