a. Complete the table above b. Compute 4 - and 5 - month moving averages for the time series. c. Compute the MAD for the 4 - and 5 - month moving averages forecasts. d. Based on the MAD error analysis, which is the preferred forecasting method? Remember that the MAD for the 3-month moving average is 6.48 . e. Use the preferred method to forecast sale of pineapples in January of the following year. f. Use a weight of 6 for the most recent observation, 3 for the second most recent, and 2 for the third most recent to compute a 3 -month weighted moving average for the time series. g. Compute the MAD for the weighted moving average in part (e). Do you prefer this weighted moving average to the 3 -month simple moving average? Remember that the MAD for the 3 -month simple moving average is 6.48
