Expert Solution

Let's do a 4-sample ANOVA for comparing the means of the 4 samples of data (assumed independent as they're all collected at different times separated by a month).

The hypothesis test is:

H0: All the means are equal, i.e. marital satisfaction stays the same over time

Ha: Marital satisfaction changes over time

Carrying out Single Factor ANOVA in Excel with alpha=0.05 (go to Data tab -> Data Analysis -> Single Factor ANOVA), we get the following output:

ANOVA
Source of Variation SS df MS F P-value F crit
Between Groups 0.06661652 3 0.02220551 0.02528605 0.99453818 2.67769903
Within Groups 108.893374 124 0.87817237
Total 108.959991 127

The p-value of 0.9945 >> 0.01, hence we cannot reject the null hypothesis that the marital satisfaction stays the same over time. Hence, the marital satisfaction stays the same over time at the 0.01 significance level.

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...
