10-4 Sampling Distribution for the Difference Between two
Independent Sample Proportions
We may be interested in comparing the proportions of two populations.
For example, we may want to compare the opinion between men and women
as to whether they agree or disagree on a particular issue. One way of doing
this, is to select a random sample of females and a random sample of males
and survey them as to whether they agree or disagree on that particular issue.
