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? 207 of the 691 couples from the study who lived together before they got married were divorced within five years of marriage. 141 of the 482 couples from the study who lived apart before they got married were divorced within five years of marriage. What can be concluded at the $\alpha = 0.10$ level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: $H_0$: Select an answer Select an answer Select an answer $H_1$: Select an answer Select an answer Select an answer b. The test statistic = ? (please show your answer to 3 decimal places.) c. The p-value = ? (Please show your answer to 4 decimal places.) d. The p-value is ? $\alpha$ e. Based on this, we should Select an answer the null hypothesis. f. Thus, the final conclusion is that.... The results are statistically insignificant at $\alpha = 0.10$, 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. The results are statistically significant at $\alpha = 0.10$, so there is sufficient evidence to conclude that the percent of the 691 couples that lived together before they got married who ended up divorced within five years of marriage is greater than the percent of the 482 couples that lived apart before they got married who ended up divorced within five years of marriage. The results are statistically significant at $\alpha = 0.10$, 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.

3. For each sequence, find the set S of subsequential limits, the limit superior, and the limit inferior. ? (a) $s_n = 1 + (-1)^n$ (b) $(t_n) = (0, \frac{1}{2}, \frac{2}{3}, \frac{1}{4}, \frac{4}{5}, \frac{1}{6}, \frac{6}{7}, \dots)$
Data from a study on exercise time per week are reviewed. The minimum is 22 min, the maximum is 344 min, and the 88th percentile is 287 min. It can then be said that: Select one: a. 287% of people do between 22 and 88 minutes of exercise per week. b. 88% of people do between 22 and 287 minutes of exercise per week c. 88% of people exercise between 287 and 344 minutes per week. d. More than 88% of people do 287 minutes of exercise in a week.
