4.5 The Carbondale Hospital is considering the purchase of a new ambulance. The decision will rest partly on the antici- pated mileage to be driven next year. The miles driven during the past 5 years are as follows: YEAR MILEAGE 3,000 4,000 3. 3,400 4 3,800 3,700 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? (IHint: You will have only 3 years of matched data.) d) Compute the forecast for year 6 using exponential smoothing. an initial forecast for year1 of 3,000 miles, and a 5. Px
