You can put this solution on YOUR website! Find the minimum sample size n needed to estimate µ for the given values of c,s, and E.
C=0.90, s=5.7, and E=2
Asume that a preliminary sample has at least 30 members.
N=__(round up to the nearest whole number.)
----
n = [zs/E}^2
----
n = [1.645*5.7/2]^2
---
n = 21.98
---
Round up to n = 22
