Fill in the blanks in the following analysis of variance table. Then compare the F-value with the critical value, using ?=0.05
| Sums of Squares | Degree of freedom | Mean Square | F | |
| Between Sums of Squares | 34.23 | 2 | ____________ | ___ |
| Within SS | ________ | ________________ | ____________ | |
| Total SS | 217.34 | 35 |
Solution
Given a=0.05, the critical value is F(0.95, df1=2, df2=33)=3.28 (from F table)
The rejection region is if F>3.28, we reject the null hypothesis.
Since F=3.084 is less than 3.28, we do not reject the null hypothesis.
| Sums of Squares | Degree of freedom | Mean Square | F | |
| Between Sums of Squares | 34.23 | 2 | 34.23/2=17.115 | 17.115/5.548788=3.084 |
| Within SS | 217.34-34.23=183.11 | 35-2=33 | 183.11/33=5.548788 | |
| Total SS | 217.34 | 35 |
