2.Go to http://finance.yahoo.com, click “DOW” on the left top corner ==> Components ==> choose a company ==> under Financials in the blue column on the left side, chose Income Statement ==> under “view”, choose “Quarterly Data”Record the four quarters’ Total Revenue and Gross Profit into Excel. Conduct bivariate plots and add in regression line, the regression equation, and R Square. (See the attachment for an example). Show your result in an attachment with your post.If we consider that equation as a formula to forecast the gross profit, what is the coefficient for x and what does it mean? What is the slope of the line for that equation and what does the slope tell us? What is the constant in the formula? What is the unit for break-even? Is your regression a good model to forecast gross profit? Why?
3.In 100+ words… Some examples of using regression analysis in business
4.What is the value of R Square? How to interpret R Square? Is your regression of the gross profit a good model? In addition, could you use the same approach to run some linear regression and solve some of equations in your professional life? Could you share some examples with the class how you will implement this technique?
