1. Compute the MSE and MAD for each forecast. Does either forecast seem superior? (Round your answers to 2 decimal places.)

2. Compute MAPE for each forecast. (Round your intermediate calculations to 6 decimal places and final answers to 4 decimal places.)

3. 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 intermediate calculations and final 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: Month 1 UWN Sales 770 789 794 780 768 772 760 775 786 790 Forecast 1 771 785 790 784 770 768 761 771 784 788 Forecast 2 769 787 792 798 774 770 759 775 788 788 6 7 8 9 10
