The forecasts and actual sales are as follows: Month Sales Forecast 1 Forecast 2 1 840 785 775 850 790 830 810 815 830 810 790 815 800 780 800 OLOVOPUT A WN 825 775 806 800 790 760 845 840 825 785 830 830 840 825 845 a. Compute the MSE and MAD for each forecast. (Round your answers to 2 decimal places.) MSE MAD Forecast 1 Forecast 2 b. Compute MAPE for each forecast. (Round your intermediate calculations to 'ecimal places and final answers to 4 decimal places.) MAPE F1 MAPE F2 % 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. (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) https://ezto.mheducation.com/api/caa/activity/C15Print?jwt=eyJhbGciOiJSUzIINiJ9.cyJIbnZpem9ubWVudC16InByb2QiLCJpc3MiOiJlenQiLCJwemludFVSTC16Im... 1/2 11/2/22, 10:39 PM Assignment Print View MSE MAD Tracking signal Control limits 0+
