Problem 34

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. One candidate finds that 52% of 473 men polled say they will vote for him, but only 45% of the 522 women in the poll express support. a) Write a 95% confidence interval for the percent of male voters who may vote for this candidate. Interpret your interval. b) Write and interpret a 95% confidence interval for the percent of female voters who may vote for him. c) Do the intervals for males and females overlap? What do you think this means about the gender gap? d) Find a 95% confidence interval for the difference in the proportions of males and females who will vote for this candidate. Interpret your interval. e) Does this interval contain zero? What does that mean? f) Why do the results in parts c and e seem contradictory? If we want to see if there is a gender gap among voters with respect to this candidate, which is the correct approach? Why?

My last job was heavily based on working in teams and providing excellent customer service. Working within groups or teams has taught me valuable skills in communicating and learning how to work with other for a common goal. The thing I liked the least about my old job were the hours/shifts. There wasn't a set amount of hours we worked a week nor were their many shifts. From June 28th - July 4th I will be out of state but from July 5th and for the duration of the summer I am available from 8:00 a.m - 10:00 p.m. Bryce Jordan Center, 11/14/2015 - 05/08/2016, & Eco- Reps, 08/19/2015 - 05/08/2-16 were both jobs located on
