21: 1
22: 1
23: 3
24: 2
25: 3

Answer 1

To determine which gas mileage values are common between the two distributions of cars and SUVs, we can list the values:

**Cars:**
- 18: 1
- 19: 2
- 20: 3
- 21: 2
- 22: 1

**SUVs:**
- 21: 1
- 22: 1
- 23: 3
- 24: 2
- 25: 3

Now we can identify the values that appear in both distributions:
- **21** (present in both cars and SUVs),
- **22** (present in both cars and SUVs).

From this, we can conclude:

The lowest value they have in common is **21**.

The highest value they have in common is **22**.
