The researcher initially fits the equation using OLS regression analysis. However, suspecting that tax evasion causes both Y and X to be substantially underestimated, the researcher adopts two alternative methods of compensating for the under-reporting:

1. The researcher adds $90 billion to the data for Y in each state and $200 billion to the data for X.

2. The researcher increases the figures for both Y and X in each state by 10 percent.
Evaluate the impact of the adjustments on the regression results.
