The answer for C was 173.3 but I need help with this question below.

Using exponential smoothing with = 0.30 and the forecast for year 1 being 3,000, the forecast for year 6 = miles (round your response to the nearest whole number).

Thank you

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: 2 Year Mileage 3.000 4.000 3.400 3,800 5 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 = 133.3 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)
