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 3,050 4,050 3,500 3,850 3,800

a)Using a 2-year moving average, the forecast for year 6 = ANSWER 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 = ANSWER 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) = ANSWER 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 0.45 and 0.55 =

ANSWER miles (round your response to one decimal place).(Hint: You will have only 3 years of matched data.)

d) Using exponential smoothing with a = 0.30 and the forecast for year 1 being 3,100, the forecast for year 6 =

ANSWER miles (round your response to the nearest

whole number).
