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)
---
n = [z*s/E]^2
Ans: Margin of Error
--------------------------------
B. Find the maximum error of estimate (E) if n = 96
96 = [1.96*13/E]^2
-----
1.96*13/E = sqrt(96)
E = (1.96*13)/sqrt(96)
---
E = 2.6005
