You can put this solution on YOUR website! Determine the sample size if sample
standard deviation s : 6, population mean : 25,
sample mean = 23 and the degree of precision is
99%
-----------
Since E = z*s/sqrt(n)
---
n = [z*s/E]^2
----
n = [2.5758*6/0.01]^2
-----
n = 1545^2
n = 2,388,563 when rounded up
