# Math Help - Estimate mean with % confidence.

1. ## Estimate mean with % confidence.

I have a homework question that I cant figure out. I am looking for the formula on how to solve.

HW question: How many students would need to be in the sample if you wanted to estimate the mean height of OCC statistics students within .05 inch with 95% confidence?

I have the sample mean and the sample standard deviation as well as N.
