A firm experienced the demand shown in the following table. Fill in the table by preparing forecasts based on a five-year moving average, a three-year moving average, and exponential smoothing ( w = 0.9 and w=0.3 ). (Note: The exponential smoothing forecasts may be begun by assuming Y^t+1=Yt.) The following table shows the square errors, (YtY^t1)2, for forecasts from 2005 through 2009. Fill the table by calculating the root mean square error (RMSE) for each of the methods
