The researchers are __?__% confident the difference between the
two population proportions,p1−p2, is between __?__and __?__.

three decimal places as needed.)
A 95% confidence interval for a difference in proportions p1-p2
if the samples have n1=60 with p^1=0.69 and n2=60 with p^2=0.56,
and the standard error is SE=0.09.
Given two independent random samples with the following
results:
n1=350 n2=475
p1=0.55 p2=0.68
Can it be concluded that the proportion found in Population 2
exceeds the proportion found in Population 1? Use a significance
level of α=0.05 for the test. Step 1 of 5 : State the null and
alternative hypotheses for the test.
