Expert Solution
Step 1

Given:

The weights are 0.15, 0.35 and 0.50.

0.50 is for the most recent period.

The provided data is:

Year 1 2 3 4 5 6 7 8 9 10 11
Demand 7 8 6 7 11 7 13 14 9 13 6

b)

Steps to calculate 3 year moving average are as follows:

1) Calculate the average demand of previous 3 years to get the moving average of the current year.
