This questiоn will аnаlyze dаta frоm the American Natiоnal Election Study which is a survey of thousands of ordinary Americans. The variables used here are: - clinton.thermometer is a respondent’s rating of their feelings toward Hillary Clinton. The scale goes from 0 (extremely negative) to 100 (extremely positive) - party.id is a respondent’s party identification that goes from 1 (strong Democrat) to 7 (strong Republican) Consider the R code and output below: a) How do these regression results predict that clinton.thermometer will change if party.id is increased by 1 unit? b) Conduct a formal hypothesis test at the α = 0.05 significance level to assess whether people with higher (more Republican) values of party.id tend to have different feelings toward Clinton on average than those with lower (more Democratic) values of party.id. Be sure to formally specify your hypotheses, describe your conclusion and briefly explain what you learned from this test. c) Form a 95% confidence interval for the slope coefficient on party.id. (you can round all numbers used in the calculation to the nearest tenth if you want to keep it simple, e.g. 1.2845 would round to 1.3; you may also use 2 as the critical value instead of 1.96)
