2.
This plot suggests that there is some positive correlation between adjusted return and risk
premium. However, there are several outliers that appear to be influential. If we exclude these
points, the correlation is a lot less apparent, and looks a lot less significant.

4. As justified by the attached hypothesis test, there appears to be a larger systematic risk
exposure in McDonald’s monthly stock return.
5.
In the versus fits graph, there appears to be four outliers that deviate visibly from the main
cluster of standardized residuals vs. fits. The outliers are data-points: 10, 22, 28, 39. The
standardized residuals appear to have no correlation and non-constant variance.
