Comparing Two Independent Population Proportions · Exercise 31

Joan Nguyen recently claimed that the proportion of college-age men with at least one pierced ear is as high as the proportion of college-age women. She conducted a survey in her classes. Out of 107 men, 20 had at least one pierced ear. Out of 92 women, 47 had at least one pierced ear. Do you believe that the proportion of men has reached the proportion of women?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
