A newly hired basketball coach promised a high-paced attack that will put more points on the board than the team's previously tepid offense historically managed. After a few months, the team owner looks at the data to test the coach's claim. He takes a sample of 25 of the team's games under the new coach and finds that they scored an average of 110 points with a standard deviation of 5 points. Over the past 10 years, the team had averaged 108 points. What is the value of the appropriate test statistic to test the new coach's claim at the 1% significance level?
