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: Month Sales Forecast 1 Forecast 2 1 830 790 820 2 840 820 800 3 810 825 825 4 845 835 805 5 795 820 795 6 830 770 806 7 805 790 755 8 840 830 785 9 840 805 785 10 800 820 850 a. Compute the MSE and MAD for each forecast. (Round your answers to 2 decimal places.) Forecast 1 Forecast 2 MSE MAD b. Compute MAPE for each forecast. (Round your intermediate calculations to 5 decimal places and final answers to 4 decimal places.) MAPE F1 MAPE F2 % % c. Prepare a naive forecast for periods 2 through 11 using the given sales data. Compute each of the following: (1) MSE, (2) MAD, (3) tracking signal at month 10, and (4) 2s control limits. (Round your answers to 2 decimal places.) MSE MAD Tracking signal Control limits 0
