Problem 3-22 (Algo) Two independent methods of forecasting based on judgment and experience have been prepared each month for the past 10 months. The forecasts and actual sales are as follows: Forecast 1 840 815 Month 1 2 3 4 5 6 7 8 9 10 Sales 840 845 795 845 780 835 775 855 845 830 795 830 790 800 785 775 795 845 Forecast 2 805 810 825 860 785 776 785 835 850 850 Compute the MSE and MAD for each forecast. (Round your answers to 2 decimal places.) MSE MAD Forecast 1 Forecast 2 Then, Compute MAPE for each forecast. (Round your intermediate calculations to 5 decimal places and final answers to 4 decimal places.) MAPE F1 % % MAPE F2 Prepare a naive forecast for periods 2 through 11 using the given sales data. Compute each of the following; (1) MSE, (2) MAD, (3) acking signal at month 10, and (4) 2s control limits. (Negative values should be indicated by a minus sign. Round your answers to 2 ecimal places.) MSE MAD Tracking signal Control limits 0+
