Two different forecasting techniques F1 and F2) were used to forecast demand for cases of bottled water. Actual demand and the two sets of forecasts are as follows: Derlod 1 2 3 4 5 G 7 B Demand 68 75 70 74 69 72 80 78 PREDICTED DEMAND 91 12 66 66 68 68 32 70 71 72 72 74 70 76 71 78 74 30 ces Click here for the Excel Data File Compute MAD for each set of forecasts. Given your results, which forecast appears to be more accurate? (Round your answers to 1 decimal place.) 40 MAD FI MAD F2 30 appears to be more accurate b. Compute the MSE for each set of forecasts. Given your results, which forecast appears to be more accurate? (Round your answers to 2 decimal places.) MSE F1 MSE F2 25.14 15.14 F2 appears to be more accurate c. In practice, either MAD OMSE would be employed to compute forecast errors. What factors might lead a manager to choose one rather than the other? Either one might already be in uso, fotos, and have passes for common control charts d. MS would be tracking References d. Compute MAPE for each data set. Which forecast appears to be more accurate? (Round your intermediate calculations and final answers to 2 decimal places.) MAPE FR MAPE F2 5.34 4.11 F2 appears to be more accurate
