The head of the engineering department at Sumner College thinks his graduates have a higher grade point average than those at Compton College.  A sample of 100 graduates is used and their mean GPA is calculated.  The results are shown below.

Sumner College Compton College
mean GPA = 3.2 mean GPA = 3.15
standard deviation = 0.75 standard deviation = 0.62
n 1 = 100 n 2 = 100
