Choose any one of the examples (not the homework problems) in the text from chapters 8, 9, 10, or 11 involving a regression and do the same regression analysis with data updated to include the most recent data you can find.  Are the conclusions drawn in the book still valid? Why or why not?

Please make your Excel spreadsheet showing your approach and an explanation of your findings either in a PowerPoint slide deck or a text document.  If you use software other than Excel, please show your inputs, commands, and syntax for this software as well as the outputs from it.
