Answer 1

Answer:

(14+25+14+28+18+17+18+14+23+22+14+18)÷12=208.5

Answer 2

Answer:

The mean of the given data will be$\frac{75}{4}$.

Step-by-step explanation:

The given data set is$14,25,14,28,18,17,18,14,23,22,14,18$.

We have to find the mean of the above data set.

• 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 set is$14,25,14,28,18,17,18,14,23,22,14,18$.  

Here,

$\text { Sum of terms }=14+25+14+28+18+14+23+22+14+18=225\\\text { Number of terms }=12$

So, the mean of the above data will be:

$\begin{array}{l}\text { Mean }=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean }=\frac{225}{12} \\\\\text { Mean }=\frac{75}{4}\end{array}$
