Assign 8 #11 PLEASE SHOW ALL WORK

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 of which of the following? With only 27 observations, the margin of error will be large. The members of the soccer team can\'t be considered a random sample of all students. Heart rates may not have a Normal distribution.

Solution

OPTION B: The members of the soccer team can\'t be considered a random sample of all students.

As soccer players may be a little different to the majority of the population, and also that it is not a random sample (but a specific part of the population), they may not represent the population well.
