The Mayo clinic recommends that people exercise 30 minutes a
day. We will assume that exercise activity levels are normally
distributed (yeah, I know they are not – but humor me....). A
researcher wants to test whether the amount of daily exercise by
vegetarians is different from that goal. To investigate this
belief, he randomly samples seven vegetarians and measures how many
minutes per day they exercise. His results are: 29, 35, 36, 33, 31,
29, and 38.
