### Questions:
#### a) Make a stem and leaf plot of the age distribution.
| Stem | Leaf |
|------|-----------------------------------|
| 1 | 6 8 |
| 2 | 0 1 1 2 2 2 3 4 4 5 6 6 7 7 7 9 |
| 3 | 0 0 1 1 2 2 3 4 4 5 5 6 7 8 9 |

| 5 | 1 3 5 6 8 |
| 6 | 3 4 |
- **Explanation:**
- The stem and leaf plot shows the distribution of ages. The "stem" represents the leading digit(s), and the "leaf" represents the trailing digit. For example, a stem of "2" and a leaf of "3" represents the number 23.
#### b) Make a frequency table with seven classes showing class limits, frequencies, and relative frequencies.
| Classes | Frequencies | Relative frequency (round to 2 decimal places) |
|---------|-------------|-----------------------------------------------|
