Question

What is the mean of the data set


3 11 7 5 14

a 8
b 9
c 10
d 11

Answer 1

A- 8.

3+11+7+5+14= 40
40/5= 8

To take the mean you add all the numbers, then divide the sum by the total of numbers. (Ex, 2 + 2 = 4. 4/2 = 2.)

Answer 2

$3 + 11 + 7 + 5 + 14 = 40 \\ 40 \div 5 = 8$
so 8 is your answer
