The Result of a Hypothesis Is Described in Terms of the Probability

Essay

The result of a hypothesis is described in terms of the probability of obtaining a particular sample. Use the given contextto formulate the null and alternative hypotheses. Discuss whether the sample provides evidence for rejecting the nullhypothesis.
-The mean resting heart rate for students at Northridge College is 72 beats per minute. An exercise physiologist believes that for athletes, the mean resting heart rate will be lower.
She finds that for a random sample of 55 athletes at the college, the mean resting heart rate is 71 beats per minute.
Assuming that the mean resting heart rate for all athletes at the college is 72 beats per minute, the probability of selecting a random sample with a mean of 71 or less beats per minute is $0.14$ .
