7-2 Final Project Part II Milestone Four: Data Analysis

Specifically, you must address these critical elements: A. Graphs: In this section, you will use graphical displays to examine the data and formulate an initial hypothesis. In particular, you should: 1. Create key graphical displays that give a sense of potential relationships between variables. Include the graphs and discuss why you selected these graphical displays as opposed to others. B. Conduct appropriate hypothesis tests, simple regressions, and other tests to analyze the data set. C. Explain why these tests are the best choice in this context and how they compare with established best practices. D. Analysis of Biostatistics: Use this section to describe your findings from a statistical standpoint. Be sure to: 1. Present key biostatistics from the graphs, tests, and regressions performed, and explain what they mean. Be sure to include a spreadsheet showing your work as an appendix. 2. What statistical inferences or conclusions can you draw based on the hypothesis tests and simple regression analyses performed? Justify your response.
