Ninetytwo students in an introductory statistics course participated in a simple experiment. The students
ﬁrst took their own pulse rates. (Could you do this? Hold your thumb and foreﬁnger of one hand onthe pair
of arteries on the side of your neck!) Each student then ﬂipped a coin. If their coin came up Heads, they
were to run in place for one minute, else they were to stand still. Then all students took their own pulses
again. Some other variables were also recorded:
