Questions to answer: 1. (1 point) Use SPSS to show two-way table of the counts of Class and Sleep_quality. Include this table in your Brightspace submission. Do not include the percentages for this part. 2. (1 point) Have SPSS produce a separate table with the joint and marginal percentages. Include this table in your Brightspace submission. 13. (2 points) Calculate proportion of subjects are classified as part of the senior group and have poor sleep quality? Show your work. Use decimal notation and round your answer to two decimal places. Is this a joint, marginal, or conditional proportion? 4. (3 points) Among subjects who are junior year, were subjects more likely to have optimal or poor sleep quality? Answer with the decimal notation and round your answer to two decimal places for each category. Show your work. Are they joint, marginal, or conditional proportion? 5. (2 points) What proportion of the subjects were classified as having borderline sleep quality group? Show your work. Use decimal notation and round your answer to two decimal places. Is this a joint, marginal, or conditional proportion? 6. (3 points) SHOW a bar graph (either by hand or with SPSS) that demonstrates the joint distribution of Sleep_quality (as% of case) for each level of Class. Explain in words what your bar graphs tell you. Include these graphs in your Brightspace submission. Are the results similar for the three graphs? 7. (2 points) Is it appropriate to do Chi-Square test here? You can run the Chi-Square test in SPSS and check the footnote in the output to determine the appropriateness of the Chi-Square procedure. Give specific reasons to explain why or why not. Include numbers used to make this decision and include the Chi-Square results in your Brightspace submission. Regardless of your answer to the previous question, please answer the following question to practice performing a Chi-Square test. 8. (6 points) Is there an association between year of class (Class) and sleep quality(sleep_quality)? State your hypotheses and give your test statistic and P-value. (Use an =0.05.) State your conclusion in terms of the problem and specify whether your results refer to the sample or the population. You should be able to use the output from the Chi-Square test for this problem.
