Gini coefficient is a statistic used to measure income inequality within nations. It ranges from 0 to 100, with higher scores indicating more inequality. At the extremes, a Gini score of 0 would mean that everyone in the country earns the exact same income, and a Gini score of 100 would mean that only one person in the country earns all the income. Some people argue that the larger a nation is, the more difficult it is to maintain a fair distribution of incomes. In other words, does income inequality increase as population size increases? You can test this question by conducting a bivariate regression on the data in the table below. Throughout calculating, and for the final answer, round to two decimals. Country (1) X: Population (in millions) (2) Y: Gini Score (3) (4) (5) (6) (7) Sweden 8 27 Ethiopia 77 29 Switzerland 14 43 Laos 6 45 UK 58 35 Russia 144 44 US 291 40 Mexico 111 46 Brazil 190 56 What is the covariation of X and Y? Hint: That is what one of the numbers of the total columns is called. Throughout calculating, and for the final answer, round to two decimals. What is the slope? Interpret the slope between population size and income inequality in a complete sentence. What is the y intercept?
