Given:

Deliveries each week: 2 4 6 8

Frequency: 3 7 5 2

Let's use the deliveries each week as the weighting.

We have:

Deliveries x Frequency:


\begin{gathered} 2\ast3\text{ + 4}\ast7\text{ + 6}\ast5\text{ + 8}\ast2\text{ } \\ =\text{ 6 + 28 + 30 + 16 = 80} \end{gathered}

Now, add up the number of deliveries each week:

2 + 4 + 6 + 8 = 20

To find the weighted mean, we have:


\text{Weighted mean = }(80)/(20)=\text{ 4}

Therefore, the weighted mean is 4

ANSWER:

Weighted mean = 4
