323, 324, 327
```

**Instructions:**
1. **Determine the Class Width:**
- Calculate the range of data.
- Divide by the number of desired classes (five).

2. **Create a Frequency Table:**
- **Components:**
- Class Limits: The range of each class.
- Class Boundaries: The values used to separate each class.
- Midpoint: The center value of each class.
- Frequency: The number of finish times in each class.
- Relative Frequency: The proportion of total finish times in each class (two decimal places).
- Cumulative Frequency: The running total of frequencies.

**Table Structure Example:**

| Class Limits | Class Boundaries | Midpoint | Frequency | Relative Frequency | Cumulative Frequency |
|--------------|------------------|----------|-----------|--------------------|----------------------|
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |

Make use of the table to clearly understand the distribution and frequency of the race finish times.
