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 1 2 3 1 5 6 Sales 845 335 795 -830 235 Forecast 800 805 820 015 270 775 765 779 30 785 Eorecast 2 765 800 805 830 780 783 775 010 820 785 700 BIS 825 10 a. Compute the MSE and MAD for each forecast (Round your answers to 2 decimal places.) MSE MAD 3050 Forecast 1 Forecast 2 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 94 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. (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) MSE MAD Tracking signal Controllimit 0+
