Suppose we have independent random samples of size n 1 = 604
and n2 = 490. The proportions of success in the two samples are
p1= .43 and p2 = .51. Find the 95% confidence interval for the
difference in the two population proportions.

From table 6.1, we see that 95% confidence
corresponds to z=1.96. Notice that the sample sizes are
each greater than 30, so we may use eqn. 8.2:
B.
So, the interval is (-.139,-.021).
