The data below lists states poverty rate, gun deaths per 100,000 people, high school graduation rate and the unemployment rate. Use a 2x2 contingency table for questions 1-3. Use the median to divide each list into 2 groups. 1) Test for independence between poverty rate and gun deaths. 2) Test for independence between high school graduation rate and gun deaths. 3) Test for independence between unemployment and gun deaths. 4) Divide the data into 3 groups by gun deaths: 0-9, 9.1-12 and 12.1-20. Use ANOVA to test the claim that the average poverty rate is the same for the three groups. Be sure to write down the mean and standard deviation for each group. 0-9 9.1-12 12.1-20 n = x = s = n = x = s = n = x = s =
