To find the range of the points scored by the football team, you need to subtract the smallest score from the largest score.
The given scores are: 17, 23, 15, 21, 7, and 13.
- Identify the largest score: 23
- Identify the smallest score: 7
- Calculate the range:
\[ \text{Range} = \text{Largest score} - \text{Smallest score} = 23 - 7 = 16 \]
Thus, the range is 16 points.
