Question
Each of the 7 cats in a pet store was weighed. Here are their weights (in pounds).13, 13, 7, 6, 13, 11, 16Find the median and mean weights of these cats.If necessary, round your answers to the nearest tenth.(a) Median: pounds(b) Mean: pounds
Solution
To find the median, you first need to arrange the weights in ascending order: 6, 7, 11, 13, 13, 13, 16. The median is the middle number, which in this case is 13.
To find the mean, you add up all the weights and then divide by the number of cats.
6 + 7 + 11 + 13 + 13 + 13 + 16 = 79
Then divide 79 by 7 (the number of cats) to get the mean.
79 ÷ 7 = 11.3
So, the median weight is 13 pounds and the mean weight is approximately 11.3 pounds.
