Use the Data Analysis Toolpak to run a simple linear regression. Explain whether the slope estimate is statistically significant using the p-value. Interpret the R-Square value. Choose one other value from the output table to interpret (not the p-value or R-Square.
Use your categorical variable and original independent variable to do a interaction variable. Now add this interaction variable to the multiple regression you ran in the last part. Explain which regression model is the "best" using the Adjusted R-Square.
