To create a frequency table starting at 20 with a class width of 4, you would set up the classes as follows:
1. **Class 1**: 20 - 23
2. **Class 2**: 24 - 27
3. **Class 3**: 28 - 31
4. **Class 4**: 32 - 35
5. **Class 5**: 36 - 39
6. **Class 6**: 40 - 43
7. **Class 7**: 44 - 47
8. **Class 8**: 48 - 51
9. **Class 9**: 52 - 55
10. **Class 10**: 56 - 59
11. **Class 11**: 60 - 63
**Note**: Since the highest age in the data you provided is 62, additional classes (like 44-47, 48-51, 52-55, 56-59, 60-63) will include no data points, but they are helpful for clarity in frequency distributions. You can stop creating classes after 60 if you prefer.
