Question

The table below summarizes the number of children per household for a sample of 47 families what is the mean number of children per household for these families round your answer to the nearest tenth

Answer 1

To find the mean, divide the product of the number of households and the number of children by the total number of households/families.

Thus, we have the following:

`\bar{x}=(8(0)+14(2)+13(3)+12(1))/(47)`

Simplifying the numerator, we have:

`\begin{gathered} \bar{x}=(0+28+39+12)/(47) \\ \bar{x}=(79)/(47) \end{gathered}`

Thus, the mean is:

`\bar{x}\approx1.68085\approx1.7`
