are you asking for $\displaystyle 1.96\sqrt{{\hat p\hat q\over n}}$ where the max occurs when we use p=q=.5?
mmm, i think so. I'm guessing the confidence interval would be 95%? heres the full Q- The Washington post surveys 1027 randomly selected people. Determine the sampling margin of error (the accuracy) for this poll using $\displaystyle \alpha=.05$
