At NC A&T, the ACT scores of entering students have had a mean of 20 (for the critical reading and mathematics portions).

A sample of 80 students in this year's class had a sample mean score of 21 and a standard deviation of 3.
Test the hypothesis that this year's class is greater than the classes before with a significance level of 0.01.
