a) Using a 2-year moving average, the forecast for year 6=3775 miles (round your response to the nearest whole number). b) If a 2-year moving average is used to make the forecast, the MAD based on this =50 miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data.) c) The forecast for year 6 using a weighted 2-year moving average with weights of 0.45 and 0.55 (the weight of 0.55 is for the most recent period) = whole number). The MAD for the forecast developed using a weighted 2-year moving average with weights of 0.45 and 0.55=67 miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data.) d) Using exponential smoothing with =0.20 and the forecast for year 1 being 3,050, the forecast for year 6= miles (round your response to the nearest whole number)
