Answer 1

32.33

Explanation:

Answer 2

32

Explanation:

To find the mean of the data set, you find the sum of the data set, and divide it by how much data you have in the data set. In this case you have 18 people (amount of data in the data set) and the sum is 35+2+7+33+25+70+75+40+42+12+15+7+44+20+25+3+65+62 = 582. So divide these two values:
`(582)/(18) = 32.\overline{33} \approx 32`
