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? 222 of the 678 couples from the study who lived together before they got married were divorced within five years of marriage. 186 of the 487 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? The test statistic ? z  = ________  (please show your answer to 3 decimal places.)   The p-value = _______  (Please show your answer to 4 decimal places.)

The proportion P residence in a community recycles traditionally been 70%. Policymaker claims of the unfortunate less than 70% now that one of the recycling centers has been relocated. It's 137 out of a random sample of 205 residence in the community said they recycle, is there enough evidence to support the policy makers claim at the 0.05 level of significance?

A random sample of n1 = 299 voters registered in the state of California showed that 140 voted in the last general election. A random sample of n2 = 220registered voters in the state of Colorado showed that 130 voted in the most recent general election. Do these data indicate that the population proportion of voter turnout in Colorado is higher than that in California? Use a 10% level of significance. What is the level of significance? What is the value of the sample test statistic? (Test the difference p1 − p2. Do not use rounded values. Round your final answer to two decimal places.) Find (or estimate) the P-value. (Round your answer to four decimal places.)

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? 217 of the 671 couples from the study who lived together before they got married were divorced within five years of marriage. 132 of the 421 couples from the study who lived apart before they got married were divorced within five years of marriage. What can be concluded at the  = 0.10 level of significance? For this study, we should use        The null and alternative hypotheses would be:                                            The test statistic     =  (please show your answer to 3 decimal places.) The p-value =  (Please show your answer to 4 decimal places.) The p-value is      Based on this, we should      the null hypothesis. Thus, the final conclusion is that ... The results are statistically insignificant at αα = 0.10, so there is statistically significant evidence to conclude that the divorce rate…

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? 212 of the 696 couples from the study who lived together before they got married were divorced within five years of marriage. 167 of the 447 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?      The test statistic  z = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.)

Suppose that you ran the following hypothesis test: H subscript o colon space p subscript 1 minus p subscript 2 less or equal than 0H subscript A colon space p subscript 1 minus p subscript 2 greater than 0 and that the data you collected produced a Test Statistic (TS), Z subscript o equals 1.68. Calculate the PValue (PV) for this TS. Round off your answer to the fourth decimal place. The PV in this hypothesis test, with the given TS and rounded off as instructed, is:

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? 268 of the 674 couples from the study who lived together before they got married were divorced within five years of marriage. 173 of the 405 couples from the study who lived apart before they got married were divorced within five years of marriage.
