Problem 1 a. Calculate three forecasts using the following data. 1. For periods 4 through 10, develop the exponentially smoothed forecasts using a forecast for period 3 (F3) of 72.0 and an alpha of 0.4. 2. Calculate the three-period moving average forecast for periods 4 through 3. Calculate the weighted moving average for periods 4 through 10, using weights of 65.25, and 10, with 0.65 applied to the most recent data. 10.
