Three-week moving average forecast

Step-by-step explanation:

Given

Solving (a): Three-week moving average forecast

This is calculated as:

Since it is three-week, we start from t = 3

For t = 3; we consider months 1, 2 and 3

For t = 4; we consider months 2, 3 and 4

For t = 5; we consider months 3, 4 and 5

So, the forecast are:

Solving (b): MSE

To do this, we simply calculate the square of the forecast error

The forecast error (E) is:

So, we have:

Forecast error                                                     The square
