Solution

The correct option is D 169.33
$\begin{matrix} Wages (xi) & 130 & 150 & 180 & 200 Number of workers (fi) & 2 & 4 & 6 & 3 \end{matrix}$

To compute the mean wage, we prepared the following table:

$\begin{matrix} xi & fi & fi xi 130 & 2 & 260 150 & 4 & 600 180 & 6 & 1080 200 & 3 & 600 total & \sum fi=N = 15 & \sum fi xi=2540 \end{matrix}$

Mean $= \frac{\sum f i x i}{\sum f i} = \frac{2540}{15} = 169.33$
