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 3000 3950 3400 3750 3700
The MAD for the forecast developed using a weighted 2-year moving average with weights of 0.40 and 0.60 = ___ miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data.)
