4 950 900
5 1,000 900
6 975 1,100
  1. Use the method stated in the text to compute the MAD and tracking signal for each week.

    Note: Negative values should be indicated by a minus sign. Round your "Tracking Signal" to 1 decimal place and all other answers to the nearest whole number.

     
  2. Decide whether the forecasting model you have been using is giving reasonable results.

    multiple choice
