1. A university with a high water bill is interested in
estimating the mean amount of time that students spend in the
shower each day. In a sample of 11 students, the average time was
5.33 minutes and the standard deviation was 1.33 minutes. Using
this sample information, construct a 99% confidence interval for
the mean amount of time that students spend in the shower each day.
Assume normality.
