Question: Defeated in his most recent attempt to win a congressional seat because of a sizeable gender gap, a politician has spent the last two years speaking out in favor of women's-rights issues. A newly released poll claims to have contacted a random sample of 120 of the politician's current supporters and found that 72 were men. In the election that he lost, exit polls indicated that 65% of those who voted for him were men. Using an a = 0.05 level of significance, test the null hypothesis that his proportion of male supporters has remained the same, Make the alternative hypothesis one-sided.
