1) Margin of Error Formula For 1 Sample Mean
2) Sample Size Calculation Given a Desired Margin of Error
* Note - Make sure to round up after calculating n. For example, if you calculate that n=82.1, the correct sample size required for the given margin or error would then be 83 NOT 82. If one were to round down, then a sample size of 82 would not guarantee the desired margin or error.
