TIOITIC WUER 3) A researcher is interested in how the financial crisis affected inequality in countries around the world. To do this, she compares countries' GINI coefficient (the standard measure of inequality in a county) in 2007 to their GINI coefficient in 2009. Larger coefficients mean greater inequality. Her data appear below. Interpret her results. Can she be 95% confident that the difference she observes is real and not simply the result of random chance?
