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
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?
