I figured out question 59 which used the test for difference of means but I'm clueless regarding question 60.
Which test would use in this question?
What is the formula?

Thanks in advance!

Look up tests of significance of difference in proportions in any stats book. Or see this http://courses.washington.edu/dphs568/course/day12.htm
