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). Round answers to 4 decimal places.

Conclusion: Select an answer The evidence suggests that the average starting hourly wages are different. There is not sufficient evidence to conclude the starting wages are different for the different groups.
