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 Mileage 1 3,050 2 4,050 3 3,450 4 3,850 5 3,700 a) Using a 2-year moving average, the forecast for year 6 = 3775 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 = 83.3 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 0.45 and 0.55 (the weight of 0.55 is for the most recent period) = 3767.5 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 0.45 and 0.55 = 103.3 miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data) d) Using exponential smoothing with a=0 30 and the forecast for year 1 being 3,050, the forecast for year 6 = 37225 miles (round your response to the nearest whole number) Enter your answer in the answer box and then click Check Answer.
