I need B, C, and D please

^{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).?The MAD for the forecast developed using a weighted 2-year moving average with weights of 0.40 and 0.60 (round your response to one decimal place). (Hint: You will have only 3 years of matched data.)?}

^{d) Using exponential smoothing with alpha ? 0.30 and the forecast for year 1 being 3,050, the forecast for year 6 (round your response to the nearest whole number).?}

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 5 follows: Year 1 2 3 4 5 Mileage 3,000 4,050 3,400 3,850 3,800 a) Using a 2-year moving average, the forecast for year 6 = 3825 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 response to one decimal place). (Hint: You will have only 3 years of matched data.)
