Question

Suppose a sample consists of the following data values. What is the sample

mean?
6, 7, 1, 9, 2, 4, 5, 5, 3, 3, 7, 8
A. 6
B. 5
C. 8
D. 7

Answer 1

B.5

Explanation:

To find the mean you have to add up all of the data values

So:

6+7+1+9+2+4+5+5+3+3+7+8 =60

Then you have to divide by the number of data values which is 12

So 60 divide by 12 = 5
