Use your statistical software package to conduct a one-factor ANOVA to determine if the group means are
equal using a = 0.01. Though not specifically assessed here, you are encouraged to also test the
assumptions, plot the group means, and interpret the results.
Group means (report to 2 decimal places):
Group 1: Internship:
Group 2: Co-op:
Group 3: Work Study:
ANOVA summary statistics:
F-ratio =
(report accurate to 3 decimal places)
p =
(report accurate to 4 decimal places)
Condusion:
O There is not sufficient data to condude the starting wages are different for the different groups.
O The sample data suggest the average starting hourly wages are not the san
same.
