The mean of a population set can be calculated through the formula:
[tex]\bar{x}=\frac{\sum ^n_{i\mathop=1}(x_i)}{n}[/tex]in which, n is the total number of data points that are in the set
then, with the sample given the mean can be found as,
[tex]\begin{gathered} \bar{x}=\frac{24+8+9+5+19}{5} \\ \bar{x}=\frac{65}{5} \\ \bar{x}=13 \end{gathered}[/tex]Answer:
The sample mean is 13.
