The Carbondale Hospital is considering the purchase of a newambulance. The decision will rest partly on the anticipated mileageto be driven next year. The miles driven during the past 5 yearsare as? follows:

???????????????????????????????????????????????????????????????????????????????????????????????????????????????  

Year	1	2	3	4	5
Mileage	3,000	4,050	3,400	3,750	3,700

?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: Youwill have only 3 years of matched? data.)

?c) The forecast for year 6 using a weighted? 2-year movingaverage with weights of 0.45 and 0.55 ?(the weight of 0.55 is forthe most recent? period) =

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

The MAD for the forecast developed using a weighted? 2-yearmoving average with weights of 0.45 and 0.55 ?=

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

?d) Using exponential smoothing with ? = 0.30 and the forecastfor year 1 being 3,050?, the forecast for year 6? =

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