Question

Find the mean of the following data:

9, 15, 17, 18, 6, 20, 8, 5, 18, 18, 10, 5, 14, 12, 10,7
A. 15
B. 12
c. 11
D. 18

Answer 1

The answer is 12 (so the letter B)

Explanation:

9+15+17+18+6+20+8+5+18+18+10+5+ 14+12+10+7=192

Then if you count the amount of numbers you find that there is 16 numbers.

You then do 192 ÷16 which gives you 12
