b) If a 2-year moving average is used to make the forecast, the MAD based on this [Select] 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) = [Select ] miles (round your response to the nearest whole number). The MAD for the forecast developed using a weighted 2-year moving average [Select] miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data). d) Using exponential smoothing with alpha a -0.4 and the forecast for year 1 being 3100, the forecast for year 6 [ Select) 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 next year. The miles driven during the past 5 years are as follows: Year Mileage 3100 1 2 3950 3 3400 4 3850 5 3800 a) Using a 2-year moving average, the forecast for year 6 3,825 miles (round your response to the nearest whole number)
