Answer 2

Answer:

The mean of the given data will be 55.

Step-by-step explanation:

Given: $9,89,79,29,69$

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 given data is$9,89,79,29,69$.

Here,

$\text { Sum of terms }=9+89+79+29+69=275\\\text { Number of terms }=5$

So, the mean of the above data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean } &=\frac{275}{5} \\\\\text { Mean } &=55\end{aligned}$
