| Mileage | 3 comma 0003,000 | 3 comma 9503,950 | 3 comma 4503,450 | 3 comma 7503,750 | 3 comma 7503,750 |
a) Using a 2-year moving average, the forecast for year 6 =

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 =
nothing
miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data.
