For the "do it" exercise that is listed as 1.3 in chapter 1, you were asked to find an annual report for a publicly traded company that shows income statements for the past two years. Take the data from the income statements and create your own excel spreadsheet that presents all of the data for year one and all of the data for year two, and add a column that presents variance between the two years, using the excel tools to compute this variance. Make sure to use effective labels on your spreadsheet for title and columns
