a. Fill in the table by preparing forecasts based on a five-year moving average, a three-year moving average, and exponential smoothing (with a w = 0.9 and a w = 0.3). Note: The exponential smoothing forecasts may be begun by assuming Yt+1 = Yt.

b. Using the forecasts from 2005 through 2009, compare the accuracy of each of the forecasting methods based on the RMSE criterion.

c. Which forecast would you have used for 2010? Why?
