Work Step by Step
**a.**
- **Set 1:** 1, 2, 4, 1, 3 (spread roughly from 1 to 4)
- **Set 2:** 9, 7, 3, 1, 0 (spread from 0 to 9)
→ **Set 2 is more variable** because its numbers cover a wider range.
**b.**
- **Set 1:** 9, 10, 12, 11 (range: 12 – 9 = 3)
- **Set 2:** 4, 5, 7, 6 (range: 7 – 4 = 3)
→ **Both sets are equally variable** (they have the same range).
**c.**
- **Set 1:** 1, 3, 9.6, 7 (range: about 9.6 – 1 = 8.6)
- **Set 2:** 14, 15, 14, 13, 14 (range: 15 – 13 = 2)
→ **Set 1 is more variable** (its values are spread out much more).
**d.**
- **Set 1:** 8, 4, 6, 3, 5 (assuming the numbers are 8, 4, 6, 3, 5; range: 8 – 3 = 5)
- **Set 2:** 4, 5, 7, 6, 15 (range: 15 – 4 = 11)
→ **Set 2 is more variable** (a larger range).
**e.**
- **Set 1:** 114, 113, 114, 112, 113 (range: 114 – 112 = 2)
- **Set 2:** 14, 13, 14, 12, 13 (range: 14 – 12 = 2)
→ **Both sets are equally variable** (they have the same spread, though one is shifted upward).
