a) Using a 2-year moving average, the forecast for year 6 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 : miles (round your response to one decimal piace). (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 0.40 and 0.60 (the weight of 0.60 is for the most recent period) = whaie number). The MAD for the forecast developed using a weighted 2-year moving average with weights of 0.40 and 0.60=93.3 miles (round your response to ane diecimal ploce). ifint: You will have only 3 years of matched data.) d) Using exponential smoothing with ix =0.40 and the forecast for year 1 being 3,050 , the forecast for year 6= miles (round your response to the nearesi whaje number)
