Question

Find the population mean or sample mean as indicated.Sample: 24, 8, 9, 5, 19

Answer 1

The mean of a population set can be calculated through the formula:

$\bar{x}=\frac{\sum ^n_{i\mathop=1}(x_i)}{n}$

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,

$\begin{gathered} \bar{x}=\frac{24+8+9+5+19}{5} \\ \bar{x}=\frac{65}{5} \\ \bar{x}=13 \end{gathered}$

Answer:

The sample mean is 13.
