Solution:
Let p1 be the proportion of men who felt the division of housework was fair and p2 be the proportion of women who felt the division of housework was fair.
The null and alternative hypotheses are:
Under the null hypothesis, the test statistic:
Where:
The p-value is:
Conclusion: Since the p-value is less than the significance level 0.05, we, therefore, reject the null hypothesis and conclude that there is sufficient evidence to support the claim that the proportion of men who felt the division of housework was fair is greater than the proportion of women who felt the division of housework was fair.
