2. Know how to do a weighted moving average as done in the textbook on p. 52

You only need to identify the regression equation and predicted sales value. You do not need to show a graph like in exhibit 3.6 on p. 58 and you do not need a table like in exhibit 3.7 on p. 59. You will not have to calculate the standard error of the estimate as shown on p. 59
