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
Part 2: Variance of simple OLS slope estimator
6. Consider the formula for Var (ß,) from a simple regression below. For the regression
estimated in Part 1, what is the value of SST, ?
Var(ß,) =
SSTx
