Answer 1

ANSWER

$undefined$

EXPLANATION

We want to find the missing value in the table.

Since the sample was taken of 40 people, then there should be 40 samples recorded in the table.

This means that to find the missing value, we have to find the sum of all the values in the table and subtract it from 40.

That is:

$\begin{gathered} 40-(4+6+8+7+3) \\ 40-(28)=40-28 \\ \Rightarrow12 \end{gathered}$

The missing value is 12.
