Answer 1

To create a relative frequency table and calculate the percentage of teenagers who prefer strawberry, you can follow these steps:

1. **Find the total number of teenagers**: According to your data, there are 300 teenagers in total.

2. **Calculate the relative frequency for teenagers who prefer strawberry**:
- Number of teenagers who prefer strawberry: 75
- Percentage of teenagers who prefer strawberry = (Number of teenagers who prefer strawberry / Total number of teenagers) * 100

\[
\text{Percentage of teenagers who prefer strawberry} = \left( \frac{75}{300} \right) \times 100 = 25\%
\]

3. **Fill in the relative frequency table for teenagers and kids**:

| Prefer | Strawberry | Vanilla | Total |
|--------------------|------------|---------|-------|
| Teenagers | 75 | 225 | 300 |
| Kids | 100 | 300 | 400 |
| Total | 175 | 525 | 700 |
| **Relative Frequency** | **%** | **%** | **%** |
| Teenagers | 25% | 75% | 100% |
| Kids | 25% | 75% | 100% |

### Summary:
