mean attendance is 88,532 people and the standard deviation is 1341 people. Ten more seasons are randomly
selected from years when the team lost more games than they won with a mean of 86,910 people and a standard
deviation of 1521 people. Assume all conditions for conducting a significance test have been met and that the p-
