The number of checks received in June was 40 million, while the forecast was 42 million. A smoothing constant of 2 is used. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 a) What is the forecast for July? b) If the center received 45 million checks in July, what would be the forecast for August? c) Why might this be an inappropriate forecasting method for this situation? 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 B2 Q1 Q2 Q3 04 Type here to search Hom File Home Insert Page Layout Formulas Data Review View Help PROTECTED VIEW Be careful-files from the Internet can contain viruses.

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: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 a) Forecast the mileage for next year (6th year) using a 2-year moving average. b) Find the MAD based on the 2-year moving average. (Hint: You will have only 3 years of matched data.) c) 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 MAD results from using this approach to forecasting? (Hint: You will have only 3 years of matched data.) d) Compute the forecast for year 6 using exponential smoothing, an initial forecast for year 1 of 3,000 miles, and a =.5.
