Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim. The owner of a football team claims that the average attendance at games is over 794, and he is therefore justified in moving the team to a city with a larger stadium. Assuming that a hypothesis test of the claim has been conducted and that the decision is failure to reject the null hypothesis, state the conclusion in nontechnical terms.

Original claim:  The mean pulse rate (in beats per minute) of a certain group of adult males is 73 bpm. The hypothesis test results in a p-value of 0.0096. Assume a significance level of α = 0.01. State a conclusion about the null hypothesis.
