In the survey of families in which both parents work, one of questions asked was, "Have you refused a job, promotion, or transfer because it would mean less time with your family?" A total of 200 men as well as 200 women were asked this question. "Yes" was the response given by 33% of men and 30% of the women. Based upon this survey, can we conclude that there is the difference in the proportion of men and women responding "yes" at the 0.05 level of significance? (Use Men - Women.)
