Math 1223 Project Part 7: Quantitative Inference with Formulas

Please use the data you originally collected for part 1. You will add these new parts to report part 2, 3, 4, 5, and 6.

1. For this project you must find some published or existing data. Possible sources include: almanacs, magazines and journal articles, textbooks, web resources, athletic teams, newspapers, professors with experimental data, campus organizations, electronic data repositories, etc. Your dataset must have at least 25 cases, two categorical variables and two quantitative variables. It is also recom- mended that you are interested in the material included in the dataset.

2. Use the techniques of the text to repeat your hypothesis test.

(a) Repeat your hypothesis test on the quantitative variable utilizing the appropriate formulas for your situation. Compute 95% confidence interval and compare to results from bootstrapping.

3. Add to your report!

(a) Include all items requested above. Include text and graphics describing the processes you have completed.

The seventh report submission will be graded by the following criteria:

• Continuation -10 points. The report includes the material from the previous reports and any errors that interfered with the cohesion of the report have been fixed.

• Statistical analysis - 10 points. The statistical tests are all provided and typeset correctly.

• Formulas - 10 points. The appropriate formula is used and included in report correctly typeset.

• Interpretations - 10 points. The results of the statistical analysis are clearly explained and interpreted in the context of the problem. The conclusions accurately reflect the analysis and are well supported.

• Writing quality - 10 points. The paper is readable and clearly written. There are few, if any, gram- matical or spelling errors and they do not interfere with the clarity of the paper.
