The monthly demand for units manufactured by the Acme Rocket Company has been as follows:Month         Units              Month              UnitsMay             100               September         105June             80                   October            110July              110                November         125August         115                December         120a. Use the exponential smoothing method to forecast the number of units for June to January. The initial forecast for May was 105 units; α = 0.2.b. Calculate the absolute percentage error for each month from June through December and the MAD and MAPE of forecast error as of the end of December.c. Calculate the tracking signal as of the end of December. What can you say about the performance of your forecasting method?
