Q1
One of the questions in a study of marital satisfaction of dual-career couples was to rate the statement, \"I'm pleased with the way we divide the responsibilities for childcare." The ratings went from 1 (strongly agree) to 5 (strongly disagree). The table below contains ten of the paired responses for husbands and wives. Conduct a hypothesis test at the 5% level to see if the mean difference in the husband's versus the wife's satisfaction level is negative (meaning that, within the partnership, the husband is happier than the wife). 5 score 3 4 2 3 4 2 1 1 2 4 Husband's score 2 1 1 3 2 1 1 1 2 4 NOTE: If you are using a Student's t-distribution for the pro alem, including for paired data, you may assume that the underlying population is normally distributed.
