Sales of Volkswagen's popular Beetle have grown steadily at auto dealerships in Nevada during the past 5 years (see table below). Using exponential smoothing with a smoothing constant (a) of 0.30 and a starting forecast of 415.00, the following sales forecast has been developed: Year Sales 2005 2006 2007 2008 2009 455 502 518 566 584 Forecasted Sales 415.00 427.00 449.50 470.05 498.84 The MAD for a forecast developed using exponential smoothing with a = 0.30 is 7:022 sales (round your response to two decimal places). Forecasted sales for years 2006 through 2010 using exponential smoothing with a = 0.60 and a starting forecast of 415.00 are (round your responses to two decimal places): 2006 2007 2008 Year Forecasted Sales 2005 415.00 2009 2010 88 4,22 The MAD for a forecast developed using exponential smoothing with a = 0.60 is 59 sales (round your response to two decimal places). Forecasted sales for years 2006 through 2010 using exponential smoothing with a = 0.90 and a starting forecast of 415.00 are (round your responses to two decimal places): 2009 2010 Year Forecasted Sales 2005 415.00 2006 464 2007 2008 499939 The MAD for a forecast developed using exponential smoothing with a = 0.90 is sales (round your response to two decimal places)
