Problem 12-21 (Algo) Given the data shown below, use a=0.2 and p = 0.4 to create a trend-enhanced exponential smoothing forecast assuming FIT1 = 26 and T1 = 4. Then use a = 0.8 and F(1) = 26 to create a simple exponential smoothing forecast. Finally, create a 2-period moving average forecast 4 Period Demand 1 27 2 33 3 37 5 29 25 a. Calculate the MFE and MAD for each model. (Round your intermediate calculations and final answers to 1 decimal place.)
