Question
This problem demonstrates a possible (though rare) situation that can occur with group comparisons. The groups are sections and the dependent variable is an exam score.

The scores for each section are as follows:

|             | Section 1 | Section 2 | Section 3 |
|--------|------------|------------|------------|
| **Score 1** |        77     |        66.9   |        80.7   |
| **Score 2** |       84.8   |        71.8   |        79.4   |
| **Score 3** |       93.3   |        88.9   |        83.3   |
| **Score 4** |       87.6   |        73.2   |        87.4   |
| **Score 5** |       89.6   |        52.8   |        76.2   |
| **Score 6** |       83.9   |        50.2   |        83.9   |
| **Score 7** |       79       |        77      |        72.5   |
| **Score 8** |       69.2   |        66      |        89.9   |
| **Score 9** |       70.9   |        92.5   |        82.5   |

Run a one-way ANOVA (fixed effect) with α = 0.05. Round the F-ratio to three decimal places and the p-value to four decimal places. Assume all population and ANOVA requirements are met.

\[ F = \_\_\_\_\_ \]

\[ p = \_\_\_\_\_ \]
