Question
Suppose that three drugs used to reduce systolic blood pressure are compared in a randomized experiment in which four people use each drug for a month. The data for the reductions in systolic blood pressure for the N = 12 participants follow.

|       | Drug 1 | Drug 2 | Drug 3 |
|-------|--------|--------|--------|
| **1** | 7      | 8      | 16     |
| **2** | 2      | 12     | 9      |
| **3** | 5      | 0      | 5      |
| **4** | 6      | 4      | 10     |

Calculate the F-statistic for comparing the mean cholesterol reductions for the three drugs. What is the value of F? [Input field] (report to 2 decimal places)

What are the degrees of freedom for this statistic - Between df? [Input field], Within df? [Input field]
