Are couples that live together before they get married just as likely to end up divorced within five years of marriage compared to couples that live apart before they get married? 184 of the 601 couples from the study who lived together before they got married were divorced within five years of marriage. 142 of the 480 couples from the study who lived apart before they got married were divorced within five years of marriage. What can be concluded at the alpha = 0.05 level of significance? If the calculator asks, be sure to use the "Pooled" data option.
For this study, we should use
z-test for the difference between two population proportions

Based on this, we should
fail to reject
Correct the null hypothesis.
