Answer 1

To find the range of the number of push-ups, we need to subtract the minimum value from the maximum value for each week.

**Week 1 Data:** 5, 8, 10, 11, 6, 8, 9, 15, 5, 8
- Maximum value: 15
- Minimum value: 5
- Range for Week 1 = Maximum - Minimum = 15 - 5 = 10

**Week 2 Data:** 7, 9, 11, 12, 8, 10, 11, 18, 9, 10
- Maximum value: 18
- Minimum value: 7
- Range for Week 2 = Maximum - Minimum = 18 - 7 = 11

So, the answers are:
- The range of the number of push-ups people did in Week 1 is **10**.
- The range of the number of push-ups people did in Week 2 is **11**.
