Month Demand 1 18 2 22 3 21 4 19 5 20 6 17 a) The MAD based on the Exponential smoothing α = 0.2 method = Blank 1 (4 decimal places) b) The MAD based on the 3 months moving average method = Blank 2 (in 4 decimal places) c) The MSE based on the 3 months moving average method = Blank 3 d) Use MAD as an criterion to evaluate forecasting methods I (exponential smoothing, α = 0.2 ) and II (3 month moving average). The most accurate forecasting methods between I and II is method Blank 4 (enter I or II)
