Enter the forecast values for periods 1-10 using a Simple 3-period Moving Average Model, a 3-period Weighted Moving Average Model with weights of (.5, .3, .2), and Simple Exponential Smoothing with alpha = .2.

(Round all forecast values to the closest integer value. Enter "0" in a field if there is insufficient data to calculate a forecast value.)

Graph the historical demand and the forecast values for each of the three approaches had they been used in the past. Based on the graph, which of the above three forecasting models would have provided more accurate forecasts had it been used in the past? Use the forecasting model with the highest anticipated accuracy to forecast demand for period 11. The demand forecast for period 11 is
