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 1 56 2 7 9 10 Sales 845 830 830 795 765 840 a. Compute the MSE and MAD for each forecast. (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 monthis The forecasts and actual sales are as follows: o. Compute the MSE and MAD for each forecast. (Round your onswers to 2 decimol places.) Answer is complete but not entirely correct. b. Compute MAPE for each forecast. (Round your intermediate calculations to 5 decimal places and final answers to 4 decimal ploces.) Answer is not complete. c. Prepate 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) 2 s control limits. (Negotive volues should be indicoted by a minus sign. Round your answers to 2 decimal places.)
