Half a century ago men were far more likely to be the breadwinner and women were far more likely to be homemakers. There are now many households where women are the breadwinners and many households where both work outside the home. Is there a difference in the proportion of men and women (SEX: 1 = Male, 2 = Female) working full time outside the home (WRKSTAT: 1 = Working full time, 2–8 = Other)? Perform a statistical test to answer the question.
