1. There are six forecasting methods presented in the chapter slides. Use the same data set below to forecast from April through December for all six methods. Also calculate error terms for each forecast. Please use an excel spreadsheet to do all of your work, and please plot the actual data below using the graph function.

   Please watch the videos if you need to see how to make the forecasts.

   Important Note: Assume you know actual values of January, February, March, and April but that you don't know actual values (even though they are given) for April through December. You only forecast the next month after the previous month is revealed.
