Question 1117916
Find the minimum sample size n needed to estimate mu for the given values of​ c, sigma​, and E.
c equals 0.95​, sigma equals 8.8​, and E equals 1
Assume that a preliminary sample has at least 30 members.
-----
Since E = z[s/sqrt(n)],
n = [z*s/E]^2
n = [1.96*8.8/1]^2
----------
n equals 298 ​(Round up to the nearest whole​ number.)
