A quality control manager wants to check the accuracy of the exponential smoothing with trend method. Using the smoothing constant alpha a =0.9 and delta õ = 0.3, find the forecast for quarters 2 and 3 using the exponential smoothing with trend method. Assume that the previous forecast (for quarter 1) including trend (FIT) was 220 units, and the previous trend component (T) was 20 units. Actual sales are given below: Period Actual Sales Quarter 1 200 Quarter 2 210 Quarter 3 190
