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:

a) Using a 2-year moving average, the forecast for year 6 = ____miles (round your response to the nearest whole number).

b) The forecast for year 6 using a weighted 2-year moving average with weights of 0.35 and 0.65 (the weight of 0.65 is for the most recent period) = miles (round your response to the nearest whole number).

c) Using exponential smoothing with alpha ? = 0.50 and the forecast for year 1 being 3,050 the forecast for year 6 = miles (round your response to the nearest whole number).

Year Mileage 1 3,050 2 4,050 3 3,400 4 3,850 5 3,750
