         ClassOf1 provides expert guidance to College, Graduate, and High school students on homework and assignment problems in
                       Math, Sciences, Finance, Marketing, Statistics, Economics, Engineering, and many other subjects.




              Construct the indicated confidence interval for the difference in proportions. Assume that the
              samples are independent and that they have been randomly selected.

              In a random sample of 300 women, 68% favored stricter gun control legislation. In a random
              sample of 200 men, 57% favored stricter gun control legislation. Construct a 98% confidence
              interval for the difference in the proportions of women and men who favor stricter gun control
              legislation.
