Consider the data in the table below. l. [n the spaoe below {or on a separate sheet of paper), plot all observations of the table above and draw the GL3 regression line. You can estimate the slope and constant of the DLS regression line by hand, with Stata, or with Ease] {you don't have to show your workings}. Don't forget to label the axes. [15 marks] 2. The slope coefficient for a regression of Y on X is . [5 marks] 3. The constant of a regression of Y on X is [5 marks] 4. The residual for the first observation in the table is [5 marks] 5. The average value of the residuals is [5 marks]
