o Two different forecasting techniques (F1 and F2) were used to forecast demand for cases of bottled water.

In practice, either MAD or MSE 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 use, familiar to users, and have past values for comparison. If are used, MSE would be natural, if are used, MAD woul d. Compute MAPE for each data set.
