Yоu hаve been discussing the Republicаn rаtiо and its cоnnection with the COVID-19 fatality ratio. You reran the regression with just the Republican Ratio (Rratio) as the independent variable and the COVID-19 case fatality ratio as the dependent variable. This simple linear regression model looks statistically significant. However, you remember to check the assumptions. One assumption you test is assumption of constant variance of the residuals. You plot the residuals against the predicted Y values and see the following output. Do the residuals reflect constant variance across the predicted Y values?
