The following three independent random samples are obtained from three normally distributed populations with equal variance. The dependent variable is starting hourly wage, and the groups are the types of position (internship, co-op, work study). We are testing that the starting salaries for new college graduate are different depending on the positions at a = :0.05 given the following data Group 1: Internship Group 2: Co-op Group 3: Work Study 11.75 11.25 10.25 11 10.75 9.5 10 9.75 11.25 12.75 11.5 12.25 12.75 11.5 12.25 14.5 10 10.5 12.75 11 9.25 1.
