- Under what conditions might a firm use multiple forecasting methods?1. Omar has heard from some of his customers that they will probably cut back on order sizes in thenext quarter. The company he works for has been reducing its sales force due to falling demand andhe worries that he could be next if his sales begin to fall off. Believing that he may be able to convince his customers not to cut back on orders, he turns in an optimistic forecast of his next quartersales to his manager. What are the pros and cons of doing that?Given the Actual Demand from January to June of 2021, along with the forecasts based on three (3) selected methods. JAN FEB MAR APR MAY JUN Actual 960 1,230 1,520 1,350 1,800 1,920 Method 1 1,308 1,073 1,150 1,467 1,425 1,682 Method 2 1,324 1,215 1,219 1,310 1,322 1,465 Method 3 867 979 1,340 1,330 1,930 2,524 From the different methods, which is best? 1, 2, or 3? py What is the MAD value of the best method? What is the MSE value of the best method? What is the MAPE value of the best method? Answer using two decimal places.
