A study of 1999 elderly Asian men cross-classified the incidence of depression with bone mineraldensity (BMD). The data were as follows:Depressiondepressednot depressed totalosteoporitic3 (35 (38BMD:low BMD69 (533 (602high BMD97 (1262 (1359total:16918301999On your exam paper, copy the table above: find the expected values ("E") and enter them next tothe observed values ("O") in the table using the parentheses provided.In the answer space below, write downa) the six expected values E andb) the chi-square test statistic associated with these data (see next question). Referring to the data in question 3 above:At the 1% significance level, do the data support the conclusion that BMD and depression arestatistically dependent in elderly Asian men? Formulate and carry out the chi-square independencetest. As usual, includea) a statement of the hypothesesb) the critical value for the testc) the value of the test statistic (from the previous question)d) a statement of conclusion

A study was performed to compare two treatment regimens for smokers who wish to stop smoking. The two treatments are: Treatment A: Use Nicorette chewing gum, which is a nicotine replacement. Treatment B: Switch to e-cigarettes. A total of 500 smokers were randomly allocated to one of the two treatments. The outcome after 12 weeks is summarised in the following contingency table. Stop Smoking Smoke Treatment Yes No Total less A 76 16 108 200 В 78 54 168 300 Total 154 70 276 500 Given: The value of the test statistic is x? = 14.269. Use a = 0.05 as the level of significance.

The Survey of Study Habits and Attitudes (SSHA) is a psychological test that measures the motivation, attitudes, and study habits of college students. Scores range from 0 to 200 and follow (approximately) a normal distribution with mean 115 and standard deviation o = 25. You suspect that incoming freshman have a mean μ, which is different from 115, since they are often excited yet anxious about entering college. To verify your suspicion, you test the following hypotheses. Ho: u 115 vs. Ha: 115 You give the SSHA to 25 incoming freshmen and find their mean score. Based on this, you reject Ho at significance level a = 0.01. Which of the following would be most helpful in assessing the practical significance of your results? O Construct a 99% confidence interval for u to see the magnitude of the difference between 115 and your sample results. O Take another sample and retest just to make sure the results are not due to chance. O Report the P-value of your test. O Test the hypotheses again,…
