UltraPure used two different techniques (F1 and F2) to forecast demand for cases of bottled water. Actual demand and the two sets of forecasts are in the table below. a. Compute MAD for each set of forecasts. Given your results, which forecast appears to be more accurate? (Round your answers to 2 decimal places.) 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.) c. Compute MAPE for each data set. Which forecast oppears to be more accurate? (Round your intermediate calculations to 2 decimal places and and final answers to 2 decimal places.)
