1 3,100
2 4,000
3 3,500
4 4,000
5 3,700

Forecast the mileage for next year using a 2-year moving average__________
Round your answer to the nearest whole number; for example, 1234

Find the MAD for your forecast in part (a)____________
Round your answer to the nearest whole number; for example, 123 .

Use a weighted 2-year moving average with weights of .4 and .6 to forecast next year's mileage. (The weight of .6 is for the most recent year.) ____________

What is the MAD of this forecast? ____________
Round your answer to the nearest whole number; for example, 123 .

Compute the forecast for year 6 using exponential smoothing, an initial forecast for year 1 of 3,100 miles, and a =.5
