Question

An individual has been exercising at a local gym for about 10 years. He always begins with a 10- to 15-minute session on the treadmill at a speed of 3.7 mph. During a 12-day period in 2010, he recorded his heart rate before using the treadmill and after 5 minutes of use. The data are shown in Table 8.37 (image attached).

The subject also recorded his heart rate at baseline and 5 minutes after starting the treadmill exercise (at a speed of 2.5 mph) in 2000. The data are shown in Table 8.38 (image attached).

Implement a test to compare the baseline heart rate initially (2000) and after 10 years of experience (2010), and report a two-sided p value.

**Change in Heart Rate Following Treadmill Use in 2010**

*Table 8.37 displays the heart rate changes from a baseline measurement to five minutes after treadmill use in 2010. Each row represents a day or session of data collection.*

| Day | Baseline | 5 min | Change |
|-----|----------|-------|--------|
| 1 | 85 | 103 | 18 |
| 2 | 77 | 92 | 15 |
| 3 | 81 | 97 | 16 |
| 4 | 81 | 96 | 15 |
| 5 | 74.5 | 93 | 18.5 |
| 6 | 83.75 | 96 | 12.25 |
| 7 | 76.5 | 93 | 16.5 |
| 8 | 77.75 | 94 | 16.25 |
| 9 | 79.25 | 90 | 10.75 |
| 10 | 84.25 | 99 | 14.75 |
| 11 | 76.5 | 94 | 17.5 |
| 12 | 84.75 | 97 | 12.25 |

- **Mean Baseline:** 80.1
- **Mean after 5 min:** 95.3
- **Mean Change:** 15.2

- **Standard Deviation (sd):**
- Baseline: 3.7
- 5 min: 3.5
- Change: 2.4

**Change in Heart Rate Following Treadmill Use in 2000**

*Table 8.38 illustrates heart rate data from a baseline measurement to five minutes after treadmill use in 2000.*

| Day | Baseline | 5 min | Day | Baseline | 5 min |
|-----|----------|-------|-----|----------|-------|
| 1 | 84 | 87 | 6 | 86 | 92 |
| 2 | 87 | 92 | 7 | 88 |
