he following data was calculated during a study on the federal poverty line. Now find the critical value(s) and sketch the rejection region for this hypothesis test at a 10% significance level: The senior director would like to test the claim that the percent of children who live in families with incomes below the federal poverty line is less than 13%. Sample size =50 children Sample proportion =0.08 Test statistic z0=−1.05 zz0.10 zz0.05 zz0.025 zz0.01 zz0.005 1.282 1.645 1.960 2.326 2.576 Use the curve below to show your answer. Select the appropriate test by dragging the blue point to a right-, left- or two-tailed diagram. Then, set the critical value(s) using the purple slider on the right. Set the test statistic by dragging the point on the x-axis.
