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. (Leave no cells blank - be certain to enter "0" wherever required. Negative answers should be indicated by a minus sign. Round your forecast answers to 1 decimal place. Then, starting with quarter 1 of year 2, use these rounded forecast values to compute the error and absolute error answers, Enter those answers to 1 decimal place also.)
