The Carbondale Hospital is considering the purchase of a new ambulance. The decision will rest partly on the anticipated mileage to be driven nex year. The miles driven during the past 5 years are as follows: a) Using a 2-year moving average, the forecast for year 6=3775 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 rosponse to one decimal place) (Hint: You with have only 3 years of matched data.) c) The forecast for year 6 using a weighted 2 -year moving average with weights of 0.40 and 0.60 (the weight of 0.60 is for the most rocent poviod) = miles (round your response to the nearest whole number). The MAD for the forcocast developed using a weighted 2-year moving average with woights of 0.40 and 0.60= nses (round your response to one docimal place). (Hint: You will have only 3 years of matched data) d) Using exponentail smoothing with a=0.30 and the forecast for yoar 1 being 3,100 , the forecast for year: 6= miles fround your response to the nearest whole number)
