The coach of a college men’s soccer team records the resting heart rates of the 27 team members. You should not trust a confidence interval for the mean resting heart rate of all male students at this college based on these data because;

(b) heart rates may not have a Normal distribution.
(c) the members of the soccer team can’t be considered a random sample of all students.
