Chapter 22, Problem 1ECP

To determine

The mean for the given data and round it to the nearest hundredth.

Answer to Problem 1ECP

The mean is $7.75$.

Explanation of Solution

Given:

The data set is 7, 8, 10, 6.

Formula used:

Formula for mean is given by,

$\text{Mean}=\frac{\text{Sum of all values}}{\text{Number of values}}$.

Calculation:

Obtain the mean as follows.

$\begin{array}{c}\text{Mean}=\frac{\text{Sum of all values}}{\text{Number of values}}\\ =\frac{7+8+10+6}{4}\\ =\frac{\text{31}}{4}\\ =7.75\end{array}$

Therefore, the mean is $7.75$.
