You will be asked to do the SET-UP for forecasts using the naive, moving average (2, 3, and 4 period), and exponential smoothing (alpha = .8) methods. Work out the set-up for these ahead of time if you wish. The Web problem will ask you to enter the set-up on the screen. Please note that the program is not very flexible and will only accept as correct entries that follow the format that it uses (i.e., commas in the right place, etc.). Whenever you get a correct answer, the on-line exercise will give you a special "answer code" which is assigned to you for each of the answers.
