Question: Gender gap Candidates for political office realize that different levels of support among men and women may be a crucial factor in determining the outcome of an election.

2. Write a 95% confidence interval for the percent of female voters who may vote for him. Interpret your interval.
3. Do the intervals for males and females overlap? What do you think this means about the gender gap?
4. Find a 95% confidence interval for the difference in the proportions of males and females who will vote for this candidate. Interpret your interval.
5. Does this interval contain zero? What does that mean?
