mean =( 11+13+17+19+23)/5

=83/5

=16.6

answer = Mean of given five observations are 16.6......

Answer 2

Answer:

The mean of the given data is$\begin{aligned}\frac{83}{5}\end{aligned}$.

Step-by-step explanation:

The given data is 11,13,17,19,23​.

We have to find the mean of the above data.

• As we know that the mean of a data set is the sum of the terms divided by the total number of terms.
• The formula to calculate the 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 11,13,17,19,23​.

Here,

$\text { Sum of terms }=11+13+17+19+23=83\\\text { Number of terms }=5$

The mean of the above data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean } &=\frac{83}{5}\end{aligned}$
