Question 11 1 pts If you were to use a 4-period weighted moving average to forecast period 8 (reference figure below; link is provided here ), which prior period should be weighted the heaviest to produce the most accurate forecast (assuming demand continues to follow a downward trend)? 470 450 430 Demand 410 370 350 1 2 3 4 5 6 7 Period Period 3 0 0 Period 4 Period 5 0 0 Period 6 Period 7 Question 12 1 pts When a conspicuous trend exists (such as what is shown in the previous question), which of the following forecasting approaches would generally provide the most accurate forecasts? Naive Simple moving average Weighted moving average Exponential smoothing Regression Question 13 1 pts You are given the following summary information for several candidate forecasts. Based solely on the information provided below, which forecast performs the best? Forecast Method Nave SMA (n=2) SMA (n=3) CFE -0.11 1.23 -4.52 Naive 2-period simple moving average 3-period simple moving average exponential smoothing They are all equal
