Question

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.

Internship	Co-op	Work Study
11.25	11	10.5
12.5	11.75	14.75
10.75	14	10.5
11.5	9.5	9.5
12.5	13.5	11
11.75	10.75	13.25
11.75	14.25	10.5
14.25	10.75	12.5
12.5	12.75	12.25
11.5	11.25	9.5
12	12.25	11.75
10.5	12	10
10.75	12	11.5
10.5	12.25	10.25
12.5	13.25	11.25
12.5	12.25	10.25
11.5	13.5	11
10	13.25	12.5

Use Excel to conduct a single-factor ANOVA to determine if the group means are equal using α=0.02α=0.02.  

Group means:
Internship:   
Co-op:   
Work Study:   

Fill in the summary table for the ANOVA test:
