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}=(\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}=(24+8+9+5+19)/(5) \\ \bar{x}=(65)/(5) \\ \bar{x}=13 \end{gathered}`

Answer:

The sample mean is 13.
