2. One of the interesting developments of the Covid pandemic has been the politicization of the vaccine. To explore this development we look at the following regression output based on data for all 50 states. The explanatory variable is the percent of the votes cast for Democratic president Joe Biden in the 2020 election. The response variable is the percent of the state's adult population who is fully vaccinated as of November 17. As an example, the data point representing Ohio is (45.24, 52.5). Use the output to answer the following questions. For the entire problem you can assume that regression assumptions are met. Coefficients: (Intercept) percent_vote 0.67964 Estimate Std. Error t value Pr(>|t|) 2.72840 0.05593 9.02 6.62e-12 *** 12.15 2.96e-16 *** 24.61108 Signif. codes: 0 ****' 0.001 **' 0.01 *' 0.05 '.' 0.1 ' ' 1 Multiple R-squared: F-statistic: 147.7 on 1 and 48 DF, Residual standard error: 4.055 on 48 degrees of freedom Adjusted R-squared: p-value: 2.955e-16 0.7547, 0.7496 Test an appropriate hypothesis at a = .05 to determine if there is a linear relationship a. between the percent of a state's votes cast for Biden and the vaccination rate. The percent who voted for Biden was 9.09 percentage points higher in Ohio than in Kentucky. How much higher of a percentage of Ohio adults would we expect to be vaccinated than Kentucky b. adults? С. What is the residual for the state of Ohio?
