Click the icon to view the table of average number of viewers, in millions, by year. a) Forecast the average number of viewers during the 2009 season using a three-period weighted moving average with weights 3, 2, and 1, applying 3 to the most recent data and 1 to the oldest data. The forecasted average number of viewers during the 2009 season is million viewers. (Round to one decimal place as needed.) b) Calculate the MAD for the forecast in part a. MAD = (Round to two decimal places as needed.) c) Forecast the average number of viewers during the 2009 season using exponential smoothing with trend adjustment. Set a = 0.4 and B = 0.3. The forecasted average number of viewers during the 2009 season is million viewers. (Round to one decimal place as needed.) d) Calculate the MAD for the forecast in part c. MAD = (Round to two decimal places as needed.) e) in which forecast do you have the most confidence? Why? Choose the correct answer below. O A. The three-period weighted moving average, because it has the lower MAD B. The exponential smoothing with trend adjustment, because it has the higher MAD C. The three-period weighted moving average, because it has the higher MAD OD. The exponential smoothing with trend adjustment, because it has the lower MAD Average number of viewers, in millions, by year Year 2000 2001 2002 2003 2004 2005 2006 2007 2008 Average Viewers 12.2 21.5 25.9 26.2 30.7 30.9 28.2 26.6 24.5 The accompanying data table shows the average number of viewers, in millions, for each season of a popular television show.
