For Exercises 15 and 16, use the grand slams data from Table 25.
15. Define the following classes: 11–15, 16–20, and 21–25. Use these classes to construct a frequency distribution.
2.2.15
| Grand slams | Frequency | Relative frequency |
|---|---|---|
| 11–15 | 6 | 6/18 = 0.3333 |
| 16–20 | 9 | 9/18 = 0.5000 |
| 21–25 | 3 | 3/18 = 0.1667 |
| Total | 18 | 18/18 = 1.0000 |
