Question
Kevin is taking a self-paced math class. His scores for each of the 18 quizzes during the academic year are shown below.

Complete the grouped relative frequency distribution for the data. (Note that we are using a class width of 5.)

Write each relative frequency as a decimal rounded to the nearest hundredth, not as a percentage.

**Quiz Scores:**
- 92, 95, 87, 87, 90
- 97, 88, 96, 85, 91
- 86, 98, 93, 98, 95
- 95, 83, 85

**Frequency Distribution Table:**

| Quiz Score | Relative Frequency |
|------------|--------------------|
| 79 to 83   |                    |
| 84 to 88   |                    |
| 89 to 93   |                    |
| 94 to 98   |                    |

- **Instructions:** Calculate the relative frequency by counting the number of scores that fall into each class range and divide by the total number of scores (18). Round each result to the nearest hundredth.
