Two different forecasting techniques were used to forecast demand for cases of bottled water in a store. Actual demand and the two sets of forecasts for seven periods are as follows: Period 1 2 3 4 5 6 7 F1 F2 Demand 66 6 3 70 72 7 70 73 (Click to select) # 73 F1 F2 67 Forecast Demand F1 69 69 70 70 71 71 71 2681 69 77 71 F2 71 67 a-1.
