In Minitab, open the data set PULSE.mtw. You may assume that these 92 students are a random sample of all undergraduates.
(a) Obtain a 95% confidence interval for µF - µM, the extent to which average pulse rates of female undergraduates exceeds that of male undergraduates. Provide a "sloppy" interpretation of your interval.
(b) What is a 95% confidence interval for µM - µF?
(c) Obtain boxplots of the two sets of pulse rates. Do they look as though they come from normal populations?
