nplete) HW Score: 40 Problem 4.5 Question He 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: 3 4 Year Mileage 1 3,100 2 4,050 5 3.700 3,500 3,800 a) Using a 2-year moving average, the forecast for year 6 = 3750 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 2ear moving average with weights of 0.45 and 0.55 (the weight of 0.55 is for the most recent period) = 3745 miles (round your response to the nearest whole number) The MAD for the forecast developed using a weighted 2-year moving average with weights of 0 45 and 0.55= miles (round your response to one decimal place). (Hint You will have only 3 years of matched data) 27
