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 followsYearMileage13,10024,00033,45043,85053,750a) Using a 2-year moving average, the forecast for year 6 = 3800 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 0.40 and 0.60 (the weight of 0.60 is for the most recent period) =miles (round your response to the nearest whole number)
