What proportion of respondents to the 2008 NES report having joined a protest march or rally? (See the previous summaries) 3. Now, specify and ﬁt a linear model of protest as predicted by GiniChange79to09.01. Tell us the results in the form of an equation. For example, if I ﬁt y ∼ x and got coeﬃcients of 2 and 3, I would write y = 2 + 3 x in answer to this question. lm1 <- lm(protest ~ GiniChange79to09.01, data = nes08gini.df) cat(paste(" \\text{protest} \\sim", paste(signif (coef (lm1), 3), c("", names(coef (lm1))[-1]), collapse = protest ∼ 0.152 + 0.0955GiniChange79to09.01 4. What does this coeﬃcient tell us about the relationship between income inequality and protest in the United States in 2008? People who live in states with where inequality has increased tend to report more protest activity than people who live in states where the inequality change has been less pronounced( notice that inequality increased in all states over this period). The coeﬃcient is the diﬀerence in proportion of people reporting that they had ever attended a protest between states that diﬀer by 1 unit on the Gini change scale. Here is a plot of the ﬁtted values and the observed values. plot(jitter(protest) ~ GiniChange79to09.01, data = nes08gini.df, cex = 0.7, col = "gray") line...

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
