A popular manufacturer of men's jeans would like to estimate the population mean of 32" length jeans.
--------------------------
The population standard deviation is known to be 0.65".
Determine the sample size needed to hold the maximum
error of the estimate to 0.5 with a confidence of 98%.
----------------------
n = [z*s/E]^2
---
n = [2.3263*0.65/0.5]^2 = 9.14
Round up to n = 10
