The coach of a college basketball team records the resting pulse rates of the team's players. A confidence interval for the mean

resting pulse rate of all collegians based on these data is of little use because __________.
A) the sample size is small, so the margin of error will be large.
B) the members of the basketball team can't be considered a random sample from the entire collegiate population.
C) many of the students on the team may refuse to respond.
D) the coach has sampled the entire population so there is no need for inference.

Answer:

B) members of the basketball team do not represent a random sample of the entire collegiate population.

Step-by-step explanation:

The coach aims to estimate a parameter of the broader population (the average resting pulse rates of all college students) using a statistic from a sample (the average resting pulse rate of the basketball players).

The confidence interval for this parameter is not useful since the sample of basketball team players lacks representation of the general collegiate population, making it non-random. Consequently, the parameter estimation will be biased.
