2.25 Bone strength for baseball players. Refer to the previous exercise. The study collected arm bone strength information for two groups of young men. The data in the previous exercise were for a control group. The second group in the study comprised men who played baseball. We know that these baseball players use their dominant arm in throwing (those who throw with their nondominant arm were excluded), so they get more arm exercise than the controls. Here are the data for the baseball players:
| ID | Nondominant | Dominant | ID | Nondominant | Dominant |
|---|---|---|---|---|---|
| 16 | 17.0 | 19.3 | 24 | 15.1 | 19.4 |
| 17 | 16.9 | 19.0 | 25 | 13.5 | 20.4 |
| 18 | 17.7 | 25.2 | 26 | 13.6 | 17.1 |
| 19 | 21.2 | 37.7 | 27 | 20.3 | 26.5 |
| 20 | 21.0 | 40.3 | 28 | 17.3 | 30.3 |
| 21 | 14.6 | 20.8 | 29 | 14.6 | 17.4 |
| 22 | 31.5 | 36.9 | 30 | 22.6 | 35.0 |
| 23 | 14.9 | 21.2 |
