D) Use exponential smoothing with alpha = 0.50

Can you help me with D and C.

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 3,050 2 4,000 3 3,450 4 3.800 5 3.750 Mileage a) Using a 2-year moving average, the forecast for year 6 = 3,775 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 = 91.7 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) = 3768 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 = miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data.)
