Question
![**Comparative Analysis of Systolic Blood Pressure Reduction by Three Drugs**
In this randomized experiment, three different drugs were tested for their effectiveness in reducing systolic blood pressure. Each drug was administered to four individuals over the course of one month. The table below provides the data on the reductions in systolic blood pressure for a total of 12 participants (N = 12).
| | Drug 1 | Drug 2 | Drug 3 |
|-------|--------|--------|--------|
| **1** | 7 | 8 | 16 |
| **2** | 2 | 12 | 9 |
| **3** | 5 | 0 | 5 |
| **4** | 6 | 4 | 10 |
**Calculations Required:**
- Calculate the overall mean (\(\bar{x}_g\))
- Determine the mean for each drug group (\(\bar{x}_1\), \(\bar{x}_2\), and \(\bar{x}_3\)).
**User Input Section:**
- What is the overall mean? [Input Box]
- What is the mean of Drug 1? [Input Box]
- What is the mean of Drug 2? [Input Box]
- What is the mean of Drug 3? [Input Box]
**Instructions:**
