Answer 2

Answer:

We will get the mean value is 17.

Step-by-step explanation:

• We have to evaluate the above expression by using the given data.

        Given data:- $19,18,15,17,18,15.$

        To find:- Value of mean.

        Solution:-

• We know that mean is an arithmetic average of all numbers.

• it is the sum of all numbers divided by the total number of observations.

        $mean =\frac{\text { Sum of all number }}{\text { Total number of observation }}$

        Therefore,

        $\begin{array}{l}\text { mean }=\frac{19+18+15+17+18+15}{6} \\\text { mean }=\frac{102}{6} \\\text { mean }=17\end{array}$

   Here the question will be to find the mean of $19,18,15,17,18,15.$
