Question

Concerned about the length of high school basketball games, the governing body for high school sports in a certain
state is investigating the possibility of shortening game length if the mean game length is greater than minutes. A
random sample of games from the current season was selected, and the sample mean game length was
minutes with a sample standard deviation of minutes.
Assuming that the distribution of game length is approximately normal, which of the following is the appropriate
probability statement for determining the -value of the hypothesis test to investigate whether the mean game length
is greater than minutes?
