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 3,400 3,850 3,800
?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 0.35 and 0.65 ?(the weight of 0.65 is for the most recent? period) = _____ 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 0.35 and 0.65 ?= ________ miles ?(round your response to one decimal? place). ?(Hint: You will have only 3 years of matched? data.)
?d) Using exponential smoothing with alphaα ?= 0.30 and the forecast for year 1 being 3,050?, the forecast for year 6? = _______ miles ?(round your response to the nearest whole? number).
