Question

In a survey of families in which both parents work, one of the 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 and 200 women were asked this question. "Yes" was the response given by 26% of the men and 23% of the women. Based on this survey, can we conclude that there is a difference in the proportion of men and women responding "yes" at the 0.05 level of significance? (Use Men − Women.)

(a) Find z. (Round your answer to two decimal places.)

Find the p-value. (Round your answer to four decimal places.)

(b) State the appropriate conclusion.
