Please indicate the formula you use to show your work. Note that you are asked to generate forecasts for multiple months; however, you are only required to explain your logic once, i.e., for one of the months, to avoid unnecessary duplication.
Create forecasted values for sales using three-period moving averages, i.e., MA(3). (6 points)
Compute the mean absolute error (MAD) for the MA(3) forecast generated. (6 points)
Use alpha = 0.2 for exponential smoothing and calculate forecasted values for months 2-7. (8 points)
