Question

What is the mean of the following list of extra credit points earned on a statistics test?

10,8,18,17,7

Answer 1

12

Explanation:

Given the data :

X : 10,8,18,17,7

The mean value of scores obtained can be obtained thus :

Mean = ΣX / n

n = sample size = 5

Mean = ΣX / n = (10+8+18+17+7) / 5

Mean = 60 / 5 = 12
