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 4 5 6 7 Sales 835 840 800 795 790 840 785 830 785 840 Forecast 1 840 800 780 795 10 775 795 770 790 840 Forecast 2 805 820 320 845 805 776 795 825 840 840 9 10 a. Compute the MSE and MAD for each forecast. (Round your answers to 2 decimal places.) MSE MAD Forecast 1 Forecast 2 ampute MAPE for each forecast.
