1. (") Develop a three-period moving average forecast for periods 13-15. 2. (*) Develop a two-period weighted moving average forecast for periods 12 through 15 . Use weights of 0.7 and 0.3 , with the most recent observation weighted higher. 3. (*) Develop an exponential smoothing forecast ( =0.25 ) for periods 11 through 15 . Assume that your forecast for period 10 was 252. For problems 4 through 6 , use the following time series data: 4. (*) Develop a three-period moving average forecast for April 2012 through January 2013. Calculate the MFE, MAD, values for April through December 2012. 5. ( ) Develop a two-period weighted moving average forecast for March 2012 through January 2013. Use weights of 0.6 and 0.4 , with the most recent observation weighted higher. Calculate the MFE, MAD, values for March through December. 6. (*) Develop an exponential smoothing forecast (=0.3) for February 2012 through January 2013. Assume that your forecast for January 2012 was 100. Caleulate the MFE, MAD, values for February through December
