For Exercises 37–40, again use the motor vehicle theft rate data from Table 27. But this time, use eight classes with class widths equal to 25. Define the leftmost class as: 20 to < 45.
39. Construct a frequency distribution.
2.2.39
| Motor vehicle theft rate | Frequency | Relative frequency |
|---|---|---|
| 20 to < 45 | 5 | 5/20 = 0.25 |
| 45 to < 70 | 6 | 6/20 = 0.30 |
| 70 to < 95 | 3 | 3/20 = 0.15 |
| 95 to < 120 | 3 | 3/20 = 0.15 |
| 120 to < 145 | 0 | 0/20 = 0.00 |
| 145 to < 170 | 1 | 1/20 = 0.05 |
| 170 to < 195 | 1 | 1/20 = 0.05 |
| 195 to < 220 | 1 | 1/20 = 0.05 |
| Total | 20 | 20/20 = 1.00 |
