To create a frequency table with seven classes, we follow these steps:

1. **Find the Range:**  
   - Maximum value: 64
   - Minimum value: 18
   - Range = \( 64 - 18 = 46 \)

2. **Determine the Class Width:**  
   - Class width = \( \frac{\text{Range}}{\text{Number of classes}} = \frac{46}{7} \approx 6.57 \)  
   - Round up to 7 (to ensure coverage of all data points).

3. **Create the Class Intervals:**  
   Start with the minimum value (18) and add the class width to determine the class intervals.

4. **Tally the Data:**  
   Go through each number and assign it to its appropriate class interval.

### Frequency Table:

| Class Interval | Frequency |
|----------------|-----------|
| 18 - 24        | 10        |
| 25 - 31        | 10        |
| 32 - 38        | 10        |
| 39 - 45        | 7         |
| 46 - 52        | 6         |
| 53 - 59        | 2         |
| 60 - 66        | 2         |

This table shows the distribution of your data into seven classes.
