The mean is 6.75

Explanation of Solution

Given:

The data set is:

8
7
5
7
4
7
6
7
8
8
8
6

Formula used:

The formula to compute the mean is:

  $\text{Mean}=\frac{\text{Sum of observations}}{\text{Number of observations}}$

The mean for the provided data set is:

  $\begin{array}{c}\text{Mean}=\frac{\text{Sum of observations}}{\text{Number of observations}}\\ =\frac{8+7+5+\mathrm{...}+6}{12}\\ =6.75\end{array}$

Thus, the mean is 6.75.
