Answer 2

Answer:

The mean of the given data will be$\begin{array}{l}\frac{17}{3}\end{array}$.

Step-by-step explanation:

The given data is 2,6,8,7,2,9​.

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 2,6,8,7,2,9​​.

Here,

$\text { Sum of terms }=2+6+8+7+2+9=34\\\text { Number of terms }=6$

So, the mean of the above data will be:

$\begin{array}{l}\text { Mean }=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean }=\frac{34}{6} \\\\\text { Mean }=\frac{17}{3}\end{array}$
