Problem 1.0.8 One candidate for political office finds that 52% of 473 men polled say they will vote for
him, but only 45% of the 522 women in the poll express support. Find a 95% confidence interval for the
difference in the proportions of males and females who will vote for this candidate. Interpret your interval.
Is there any evidence that difference is not equal to 1%?
