a) Using a 2-year moving average, the forecast for year 6 = 3,775 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 = 133.3 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 0.40 and 0.60 (the weight of 0.60 is for the most recent period) = 3.770 miles (round your response to the nearest whole number). 173.3 miles (round your response to one decimal dul The MAD for the forecast developed using a weighted 2-year moving average with weights of 0.40 and 0.60 place). (Hint: You will have only 3 years of matched data.) d) Using exponential smoothing with a = 0.20 and the forecast for year 1 being 3,100, the forecast for year 6 = 3,478 miles (round your response to the nearest whole number). The Carbondale Hospital is considering the purchase of a new ambulance. The decision will rest partly on the anticipated mileage to be driven new driven during the past 5 years are as follows: 1 2 3 4 5 Year Mileage 3,050 4,050 3,450 3,800 3,750 a) Using a 2-year moving average, the forecast for year 6 = miles (round your response to the nearest whole number)
