Question

just need the answer to Q5 please. I have attached my answers to 1-4

Part 1: OLS basics Consider the data in the table below. Y X 3 1 8. 3 2 1 7 1. In the space below (or on a separate sheet of paper), plot all observations of the table above and draw the OLS regression line. You can estimate the slope and constant of the OLS regression line by hand, with Stata, or with Excel (you don't have to show your workings). Don't forget to label the axes. 2. The slope coefficient for a regression of Y on X is 3. The constant of a regression of Y on X is 4. The residual for the first observation in the table is 5. The average value of the residuals is
