3. You are interested in studying systemic racism in the United States and gather data on 825 residential neighborhoods throughout the country. The two variables which interest you are the quality of the neighborhood (a composite measure of the neighborhood's noise, pollution, crime, available services, and open space) and the neighborhood's proportion of non-whites. Perform a hypothesis test at 99% confidence to see if the quality is significantly related to the racial composition of the neighborhood (25 pts). Proportion non-white Low Medium High Total Neighborhood quality 56 117 156 329 Low 89 78 34 201 Medium 231 45 19 295 High 376 240 209 825 Total
