Hi I need help with figuring out part C.

I also wanted to know what the MAD forecast would be.

Homework: Chapter 4 Homework Question 7, Problem 4.5 Part 3 of 5 HW Score: 77.11%, 48.58 of 63 points Points: 1.8 of 3 Save 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: 1 2 4 Year Mileage 3 3,450 5 3,800 3,100 4,050 3,800 a) Using a 2-year moving average, the forecast for year 6 = 3800 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 = 116.7 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 0.40 and 0.60 (the weight of 0.60 is for the most recent period) = miles (round your response to the nearest whole number)
