Are couples that live together before they get married less likely to end up divorced within five years of marriage compared to couples that live apart before they get married? 254 of the 646 couples from the study who lived together before they got married were divorced within five years of marriage. 189 of the 427 couples from the study who lived apart before they got married were divorced within five years of marriage. What can be concluded at the = 0.05 level of significance? For this study, we should use [z-test for the difference between two population proportions Ho: p1 8 a. The null and alternative hypotheses would be: H₁: p1 8 b. The test statistic c. The p-value - 0.1505 Or p2 p2 (please show your answer to 3 decimal places.) X (Please show your answer to 4 decimal places.)
