Answer 2

Answer:

The mean of the given data will be$\begin{aligned}\frac{36}{7}\end{aligned}$.

Step-by-step explanation:

The given data is 7,4,9,2,1,8,5.

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 7,4,9,2,1,8,5.

Here,

$\text { Sum of terms }=7+4+9+2+1+8+5=36\\\text { Number of terms }=7$

So, the mean of the above data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\text { Mean } &=\frac{36}{7}\end{aligned}$
