If required, round your answers to two decimal places. MSE for four-week moving average = MSE for five-week moving average = (c) What appears to be the best number of weeks of past data (three, four or five) to use in the moving average computation? Consider that the MSE for the three-week moving average is 12.852. - Select your answer -
