You can put this solution on YOUR website! 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.)
