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: Sales 840 Month 1 2 3 4 5 6 7 8 9 10 840 840 835 765 830 795 850 845 785 Forecast 1 830 800 780 825 765 795 780 785 820 810 Forecast 2 785 800 850 815 790 786 815 785 835 820 a.
