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 1 2 3 4 5 Mileage a) Using a 2-year moving average, the forecast for year 6 = 3725 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 and (the weight of is for the most recent period) = 3720 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 and = nothing miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data.)
