Final answer:
The mean weight of the cats is found by summing the individual weights and dividing by the number of cats. After doing the calculation, the mean weight is determined to be approximately 12.71 pounds.
Step-by-step explanation:
The mean weight of the cats can be calculated by adding the weight of all cats and then dividing by the number of cats. We add the weights: 15 + 10 + 8 + 12 + 15 + 15 + 14 to get a total weight of 89 pounds. Since there are 7 cats, we divide this total by 7 to find the mean weight.
Mean weight = Total weight of all cats / Number of cats
Mean weight = 89 pounds / 7 cats
Mean weight = 12.71 pounds
Therefore, the mean weight of the cats is approximately 12.71 pounds.
