To calculate the range of weights of the cats, you need to find the difference between the maximum and minimum weights.
First, identify the maximum and minimum weights from the provided data:
Weights: 9, 8, 14, 7, 8, 10, 12, 11, 15, 18, 17, 10
- Maximum weight = 18 pounds
- Minimum weight = 7 pounds
Now, calculate the range:
Range = Maximum weight - Minimum weight Range = 18 - 7 = 11
Thus, the range of weights of the cats is 11 pounds.
