For problems 1 through 3, use the following time series data: 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 1 through 3, use the following time series data: 1.
