For Exercises 25–28, again use the imports from data from Table 26. But this time, use seven classes with class widths equal to 1.5. Let the leftmost class be: 2.0 to < 3.5.
27. Construct a frequency distribution.
2.2.27
| Imports from | Frequency | Relative frequency |
|---|---|---|
| 2 to < 3.5 | 2 | 2/9 = 0.2222 |
| 3.5 to < 5 | 4 | 4/9 = 0.4444 |
| 5 to < 6.5 | 1 | 1/9 = 0.1111 |
| 6.5 to < 8 | 0 | 0/9 = 0.0000 |
| 8 to < 9.5 | 0 | 0/9 = 0.0000 |
| 9.5 to < 11 | 1 | 1/9 = 0.1111 |
| 11 to < 12.5 | 1 | 1/9 = 0.1111 |
| Total | 9 | 9/9 = 1.0000 |
