The Carbondale Hospital is considering the purchase of ambulance. The TheXarbondale Hospital is considering the purchase of ambulance. The decision will rest partly on the anticipated mileage" be driven next year. The miles driven during the past 5
years are as follows

Year Mileage
1 3000
2 3950
3 3450
4 3800
5 3800

a) Using a 2-year moving average, the forecast for year 6 = 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 = 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 0.450.45 and 0.550.55 (the weight of 0.550.55 is for the most recent period) = miles (round your response to the nearest wholenumber).

The MAD for the forecast developed using a weighted 2-year moving average with weights of 0.450.45 and 0.550.55 = ___ miles (round your response to one decimalplace). (Hint: You will have only 3 years of matched data.)

d) Using exponential smoothing with alphaα = 0.200.20 and the forecast for year 1 being 3 comma 0003,000, the forecast for year 6 = miles (round your response to the nearest whole number).
