a) The forecast for weeks 2 through 10 using exponential smoothing with =0.60 and a week 1 initial forecast of 21.0 are (round your responses fo fwo decimal places): b) For the forecast developed using exponential smoothing (=0.60 and initial forecast 21.0), the MAD = 5.09 sales (round your response to two decimal places). c) For the forecast developed using exponential smoothing ( =0.60 and initial forecast 21,0 ), the tracking signal = (round your response to two decimal places). a) The forecast for weeks 2 through 10 using exponential smoothing with =0.60 and a week 1 initial forecast of 21.0 are (round your responses fo fwo decimal places): b) For the forecast developed using exponential smoothing (=0.60 and initial forecast 21.0), the MAD = 5.09 sales (round your response to two decimal places). c) For the forecast developed using exponential smoothing ( =0.60 and initial forecast 21,0 ), the tracking signal = (round your response to two decimal places)
