Question

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).

Group 1: Internship	Group 2: Co-op	Group 3: Work Study
9	10.5	11.75
10.25	12.25	11
10.5	10.25	11.75
12.25	9	12.25
9	9.75	9.75
11.25	9.25	14.25
9.75	12.5	12.25

Use technology to conduct a one-factor ANOVA to determine if the group means are equal using α=0.01α=0.01.

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=p=
(report accurate to 4 decimal places)

Conclusion:

• There is not sufficient data to conclude the starting wages are different for the different groups.
• The sample data suggest the average starting hourly wages are not the same.

Answer 1

the above is the excel ouptut of anova (single factor ) for the groups given groups

from the output

group means are

F- ratio

2.936389685

P-value

0.078763623

p value greater than 0.01 so fail to reject H0

Conclusion:

• There is not sufficient data to conclude the starting wages are different for the different groups.
