Answer 2

Answer:

The mean of the given data will be$\frac{19}{3}$.

Step-by-step explanation:

The given data set is$8,7,3,9,6,5,7,5,7$.

We have to find the mean of the above data set.

• As we know, the mean of a data set is the sum of the terms divided by the total number of terms.
• The formula for mean is:

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

We are solving in the following way:

We have,

The given data set is$8,7,3,9,6,5,7,5,7$.  

Here,

$\text { Sum\ of terms }=8+7+3+9+6+5+7+5+7=57\\\text { Number of terms }=9$

So, the mean of the above data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean } &=\frac{57}{9} \\\\\text { Mean } &=\frac{19}{3}\end{aligned}$
