Problem 12-21 (Algo) Given the data shown below, use a = 0.2 and B=0.3 to create a trend-enhanced exponential smoothing forecast assuming FIT4 = 31 and Ty 4. Then use a=0.5 and F(1) - 31 to create a simple exponential smoothing forecast. Finally, create a 2-period moving average forecast Period Demand 1 32 2 35 3 32 4 36 41 a. Calculate the MFE and MAD for each model (Round your intermediate calculations and final answers to 1 decimal place.) Answer is complete but not entirely correct.
