a. Compute the MSE and MAD for each forecast. (Round your answers to 2 decimal places.)

b. Compute MAPE for each forecast. (Round your intermediate calculations to 5 decimal places and final answers to 4 decimal places.)

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.)

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 1 895 800 Forecast 2 775 820 845 785 81e Month 1 2 3 4 5 6 7 8 9 10 Sales 835 845 790 830 795 835 825 850 825 790 800 895 810 795 830 895 810 780 816 805 880 820 835 a.
