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: 2 4 5 year mileage 3,050 4,000 3,500 3,850 3,750

a) using a 2-year moving average, the forecast for year 6 = 3750 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 = 66.7 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) = 3735 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 = 121 comma 7 miles (round your response to one decimal place). (hint: you will have only 3 years of matched data.)
