Help with the last part. what is the MAD for the forecast

The Carbondale Hospital is considering the purchase of a new ambulance. The decision will rest partly on the anticipated mileage to be driven ney year. The miles driven during the past 5 years are as follows: 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 movina average is used to make the forecast, tha MAD based on this = You will have only 3 years of matched data) miles (round your response to one decima/ place). (Hili c) The forecast for year 6 using a weightod 2-year moving average with weights of 0.40 and 0.60 (the weight of 0.60 is for the most recent period) = - 9780 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 0.40 and 0.60= miles fround your response fo one declmat ptace), (Hint You will have only 3 years of matched data)
