Are couples that live together before they get married more likely to end up divorced within five years of marriage compared to couples that live apart before they get married? 260 of the 681 couples from the study who lived together before they got married were divorced within five years of marriage. 171 of the 474 couples from the study who lived apart before they got married were divorced within five years of marriage. What can be concluded at the a = 0.10 level of significance? For this study, we should use Select an answer a. The null and alternativ Select an answer test for the difference between two dependent population means Họ: Select an answer H: Select an answer ♥Etest for a population mean b. The test statistic test for the difference between two independent population means c. The p-value - d. The p-value is ? ♥ e. Based on this, we shoul z-test for a population proportion f. Thus, the final conclusi O The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude that the percent of all couples that live together before they get married who end up divorced within five years of marriage is greater than the percent of all couples that live apart before they get married who end up divorced within five years of marriage. O The results are statistically insignificant at a = 0.10, so there is insufficient evidence to z-test for the difference between two population proportions
