Veterans' Marital Problems (cont.) Refer to the study mentioned in Activity 18-12. u.s. Census figures indicate that among all American men aged 30-44 in 1985, 27% had been divorced at least once. Conduct a test of significance to assess whether the sample data from the study provide strong evidence that the divorce rate among Vietnam veterans is higher than 27%. Report the null and alternative hypotheses (identifying whatever symbols you introduce) and the test statistic and p-value. Also write a one-sentence conclusion and explain why the conclusion follows from the test results. Activity 18-12 Researchers recently found that in a sample of 2101 Vietnam veterans, 777 had been divorced at least once. (a) Use this sample information to form a confidence interval for the proportion of divorced men among all Vietnam veterans. (b) Would it be legitimate to use this interval as an estimate of the divorce rate among all middle-aged American men? Explain.
