a. Given the data shown above, beginning in quarter 1 of year 2, use a moving average based on four quarters to predict the demand in each quarter.

b. Using the same data, forecast demand using exponential smoothing. You are given an initial forecast for year 1, quarter 1 of 17. When generating your forecasts, assume that the smoothing coefficient is 0.10.

c. Which of the forecasting procedures performed the best? Why? Hint: Plot the demand data to better understand what is going on.
