Conduct a linear regression of new cases per capita on re-opening approach (delayed vs. early). Copy and paste the STATA output. State the regression coefficient for the re-opening approach variable. How does it compare to the difference in mean number of new cases per capita between these two groups of states

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
