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? 256 of the 668 couples from the study who lived together before they got married were divorced within five years of marriage. 185 of the 476 couples from the study who lived apart before they got married were divorced within five years of marriage. What can be concluded at the = 0.01 level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: Ho: H1: Select an answer Select an answer o Select an answer Select an answer Select an answer O Select an answer O (please show your answer to 3 decimal places.) b. The test statistic ? C c. The p-value d. The p-value is a e. Based on this, we should Select an answer the null hypothesis. f. Thus, the final conclusion is that ... O (Please show your answer to 4 decimal places.) O The results are statistically insignificant at a = 0.01, so there is insufficient evidence to conclude the percent of all couples that live together before they get married who end up divorced within five years of marriage is smaller 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 significant at a = 0.01, 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 smaller 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 = 0.01, so there is statistically significant evidence to conclude that the divorce rate for all couples that live together before they get married is equal to the divorce rate for all couples that live apart before they get married. O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the percent of the 668 couples that lived together before they got married who ended up divorced within five years of marriage is smaller than the percent of the 476 couples that lived apart before they got married who ended up divorced within five years of marriage.
