Sales of Chevrolet's popular Camaro have grown steadily at auto dealerships in Alberta during 5 years (see table below). Using exponential smoothing with a smoothing constant () of 0.30 and a starting forecast of 410.00 , the following sales forecast has been developed: Using smoothing constants of 0.60 and 0.90 , develop forecasts for the sales of Chevrolet Camaros. What effect did the smoothing constant have on the forecast? Use MAD to determine which of the three smoothing constants (0.30,0.60, or 0.90) gives the most accurate forecast. The MAD for a forecast developed using exponential smoothing with =0.30 is sales (round your response to two decimal places). Forecasted sales for years 2 through 6 using exponential smoothing with =0.60 and a starting forecast of 410.00 are as follows (round your responses to two decimal places): FY The MAD for a forecast developed using exponential smoothing with =0.60 is sales (round your response to two decimal places). Forecasted sales for years 2 through 6 using exponential smoothing with =0.90 and a starting forecast of 410.00 are as follows (round your responses to two decimal places): The MAD for a forecast developed using exponential smoothing with =0.90 is sales (round your response to two decimal places). Because it gives the lowest MAD, the smoothing constant of = gives the most accurate forecast
