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 1 3,050 2 3,950 3 3,400 4 3,800 5 3,700 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 = 108.3 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 0.45 and 0.55 (the weight of 0 55 is for the most recent period) = 3,745 miles (round your response to the nearest whole numbe 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 c
