Answer:
31 is the range.
31.625 is the mean.
Explanation:
- Range - The difference of the largest number and the smallest number.
- Mean - To calculate the mean, add up all the numbers, then, divide the sum by the count.

Now that we know the definitions, we can solve this.
21, 24, 26, 28, 32, 34, 36, 52
The largest number is 52; the smallest number is 21.
52 - 21 = 31
31 is the range.
-------------------------------------------------------------------------------------------------------------
21 + 24 + 26 + 28 + 32 + 34 + 36 + 52 = 253
There are 8 numbers in this data set.
253 ÷ 8 = 31.625
31.625 is the mean.
