Answer 2

Hello!

Let's review what mean and range is.

REVIEW

Mean is calculated by adding all the numbers and dividing by how many numbers there are.

Range is calculated by subtracting the lowest number from the greatest number, also known as finding the difference

_____________________________________________________________

Mean

18 + 23 + 10 + 39 + 22 + 17 + 16 + 15 = 160

There are 8 numbers.

Divide 160 by 8 to get the mean

160 ÷ 8 = 20

The mean is 20

___________________________________________________________

Range

The highest number is 39, while the lowest number is 10. Subtract 10 from 39 to get the range.

39 - 10 = 29

The range is 29

Your answer is the 2nd option.
