Given a level of confidence of 99% and a population standard deviation of 4, what other information is necessary:

(A) To find the Maximum Error of Estimate (E)?

(B) To find the sample size (n)?

(C) Given the above confidence level and population standard deviation, find the Maximum Error of Estimate (E) if n = 60. Show all your calculations.

(D) For this same sample of n = 60, what is the width of the confidence interval around the population mean?

(E) Given this same confidence level and standard deviation, find n if E = 3.5. (Always round to the nearest whole person.)
