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 3,000 2 3,950 3 3,450 4 5 3,750 3,700 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 58.3 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) = miles (round your response to the nearest whole number)..
