Lynfield and McWilliams (1970) did a small experiment to test for an effect of shaving. Five men shaved one leg (Test) weekly for several months while leaving the other leg unshaved (Control). The researchers measured the change in leg hair width on each of the legs. These data are given in "legshaving.csv". Was the mean hair width different in the shaved leg (Test) compared to the unshaved leg (Control)? Do all relevant analyses
