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	3,000	4,000	3,500	3,800	3,750

Part 2

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

37753775

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 =

5050

miles (round your response to one decimal place). (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

0.45

and

0.55

(the weight of

0.55

is for the most recent period) =

37733773

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

Part 5

The MAD for the forecast developed using a weighted 2-year moving average with weights of

0.45

and

0.55

=

70.070.0

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

Part 6

d) Using exponential smoothing with

=

0.50

and the forecast for year 1 being

3,000,

the forecast for year 6 =
