Given the level of confidence of 99% and population standard deviation of 10, what other information is vital:

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

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

C) Given the above confidence level and population standard deviation, find out the Maximum Error of Estimate (E) if n = 45.  Show all your computation. Show all work.

D) For this same sample of n = 45, find out the width of confidence interval around population mean?  Show all work.

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