The Wall Street Journalrecently published an article indicating differences in perception of sexual harassment on the job between men and women. The article claimed that women perceived the problem to be much more prevalent than did men. One question asked of both men and women was: "Do you think sexual harassment is a major problem in the American workplace?" 24% of the men compared to 62% of the women responded "Yes".Suppose that 150 women and 200 men were interviewed.

a)What are the null and alternative hypotheses thatTheWall Street Journalshould test in order to show that its claim is true?
