Question

In a 2013 Pew Poll, 36% of Republicans and 28% of Democrats agreed with the statement “Obesity impacts individuals, but doesn’t have a major impact on society.” A 95% confidence interval for the difference in these proportions is (-0.13 to -0.02), or, in terms of percentage points, (-13% to -2%). (Use the Democrats as population 1.) Interpret this confidence interval. If the interval contains 0, indicate what this means. Explain the meaning of positive and/or negative values.
