| Consider the following cumulative relative frequency distribution. |
| Class | Cumulative Relative Frequency |
| 150 up to 200 | 0.21 |
| 200 up to 250 | 0.28 |
| 250 up to 300 | 0.51 |
| 300 up to 350 | 1.00 |
| a-1. | Construct a relative frequency distribution. (Round your answers to 2 decimal places.) |
| Class | Relative Frequency |
| 150 up to 200 | |
| 200 up to 250 | |
| 250 up to 300 | |
| 300 up to 350 | |

| a-2. | What percent of the observations are at least 300 but less than 350? |
| Percent of observations |
| Consider the following cumulative relative frequency distribution. |
Solution
a-1.
Note that to get the relative frequencies, we simply subtract the consecutive cumulative frequency values.
Thus, consider the table:
a-2.
As we can see in the table, those at least 300 but less than 350 is 49% of the observations. [ANSWER, 49%]
| Class | Relative Frequency |
| 150-200 | 0.21 |
| 200-250 | 0.07 |
| 250-300 | 0.23 |
| 300-350 | 0.49 |
| Total | 1 |
