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? 215 of the 628 couples from the study who lived together before they got married were divorced within five years of marriage. 123 of the 467 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 = 0.05 level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: Ho: Select an answer Select an answer Select an answer H1: Select an answer Select an answer Select an answer b. The test statistic ? v = (please show your answer to 3 decimal places.) c. The p-value = d. The p-value is ? a e. Based on this, we should Select an answer f. Thus, the final conclusion is that ... (Please show your answer to 4 decimal places.) the null hypothesis.

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? 215 of the 628 couples from the study who lived together before they got married were divorced within five years of marriage. 123 of the 467 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 = 0.05 level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: Ho: Select an answer v Select an answer v Select an answer v Hj: Select an answer v Select an answer v Select an answer v b. The test statistic ? v = (please show your answer to 3 decimal places.) c. The p-value = d. The p-value is ? v a e. Based on this, we should Select an answer v the null hypothesis. f. Thus, the final conclusion is that ... (Please show your answer to 4 decimal places.) O The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the percent of the 628 couples that lived together before they got married who ended up divorced within five years of marriage is not the same as the percent of the 467 couples that lived apart before they got married who ended up divorced within five years of marriage. O The results are statistically insignificant at a = 0.05, 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 not the same as 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 = 0.05, 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 = 0.05, 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 not the same as the percent of all couples that live apart before they get married who end up divorced within five years of marriage.
