The following three independent random samples are obtained from three normally distributed populations
with equal variances. The dependent variable is starting hourly wage, and the groups are the types of
position (internship, co-op, work study). We are testing the claim that position is a factor in starting
salaries for new college graduates. at a = 0.05 given the following data
