Please use the data, StatCrunch, and your knowledge of statistics to answer the questions below.. Download the provided CDC data into StatCrunch (located at the bottom of these directions). You will utilize this data in weeks 3 and 8 for your Healthcare Applications Assignment.
Part I
Calculate the correlation coefficient between each of the independent variables and the variable—diabetes. What does this value tell us about the relationship between each of the independent variables and diabetes?
Run a regression using diabetes as the dependent variable and smoking as the independent variable.
Is there a statistically significant relationship between poverty rates and diabetes? (Use the T-stat or P-value.) Explain.
Write out the regression line calculated using the data.
Interpret b1 (the slope coefficient).
Suppose a state raises the tobacco tax and the rate of smoking in the state falls from 21% to 18%. What would the decrease be in the rate of diabetes based on the regression results?

Part II
Suppose you work for a local hospital. Your manager requests that you use the CDC data on diabetes and smoking, obesity rate, physical activity, and poverty rate to present a compelling argument to the board regarding the importance of creating state initiatives to reduce diabetes rates. You must present statistical data in a written report to the board. Write an APA formatted paper, double spaced, 2-4 pages in length, with a cover page and references page addressing the following:
Include a minimum of four types of statistical tests to make your case. Examples include hypothesis tests, confidence intervals, correlations, regressions, etc. You may use statistical tests that you have completed in weeks 3 and 8 or develop your own.
Include a minimum of three graphs with your report. Examples include scatter plots, histograms, regression lines, box-plots, etc. You may use graphs that you have completed in weeks 3 and 8 or develop your own.
Write an essay using these statistics and graphs to make a convincing argument for the need to create an initiative to reduce the rate of diabetes. In your essay, explain the relationship between diabetes and obesity, smoking, physical activity, and poverty rates utilizing statistical data, tests, and graphs. Be sure to explain your results and how these results show there is a need to create an initiative to reduce the diabetes rates.
You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.
Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.
Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.
The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
