Question

Each of the 8 cats in a pet store was weighed. Here are their weights (in pounds).
13, 12, 12, 6, 13, 8, 15, 15
Find the median and mean weights of these cats.
If necessary, round your answers to the nearest tenth.

Answer 1

To find the median weight, we must first arrange the weights in ascending order: 6, 8, 12, 12, 13, 13, 15, 15
Therefore, the median weight is the average of the two middle values: (12 + 13) / 2 = 12.5 pounds.

To find the mean weight, we must sum up all the weights and divide by the total number of cats:
(6 + 8 + 12 + 12 + 13 + 13 + 15 + 15) / 8 = 94 / 8 = 11.8 pounds.

Therefore, the median weight is 12.5 pounds and the mean weight is 11.8 pounds.
