Answer 2

Answer:

The mean of the given data will be$\frac{21}{5}$.

Step-by-step explanation:

The given data is 1,2,5,6,7​.

We have to find the mean of the above data.

• 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 data is 1,2,5,6,7​.

Here,

$\text { Sum of terms }=1+2+5+6+7=21\\\text { Number of terms }=5$

So, the mean of the above data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\text { Mean } &=\frac{21}{5}\end{aligned}$
