(= easy: ** = moderate; *** advanced) Problems for Section 9.5: Time Series Forecasting Models Basic Problems 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 fore- cast 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 (a = 0.25) for periods 11 through 15. Assume that your forecast for period 10 was 252.
