Given a level of confidence of 95% and a population standard deviation of 13, answer the following:
(A) What other information is necessary to find the sample size (n)?
(B) Find the Maximum Error of Estimate (E) if n = 82.
Part (A): You will need E (Maximum Error of Estimate)
Part (B): 82 = [(1.96 * 13)/E]^2
Solve for E.
I hope this will help get you started.
