Last month a random sample of adult American females was taken and 750 of the 1200 women polled said that they approved of the way the president was handling domestic issues. Create a 95% confidence interval for this data.
------
p-hat = 750/1200 = 0.625
----
ME = 1.96*sqrt[0.625*0.375/1200] = 0.0274
-----
95% CI: 0.625-0.0274 < p < 0.625+0.0274
