     •   Calculate a point estimate and a 95% confidence interval of the mean.   Assuming your data set is normally distributed, determine an appropriate   sample size if the maximum allowable error is three units for your data set.   Follow a 90% confidence level to determine your sample size. Note. The three   units are measured in the unit of measurement of your data set, for example   hours, pounds, or dollars.
