Using the Formulan=1ME2

to Determine Sample Size

When we want 95% confidence and use the conservative estimate ofp= 0.5, we can use the simple formulan=1ME2

to roughly determine the sample size needed for a given margin of errorME. Use this formula to determine the sample size needed for a margin of error of0.02.

Enter the exact answer. n=
