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 asfollows:

Year	1	2	3	4	5
Mileage	3,000	4,050	3,400	3,850	3,700

Part 2

a) Using a 2-year moving average, the forecast for year 6 =

miles (round your response to the nearest whole number).

Part 3

b) If a 2-year moving average is used to make the forecast, the MAD based on this =

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

Part 4

c) The forecast for year 6 using a weighted 2-year moving average with weights of

(the weight of

0.60

is for the most recent period) =
