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?
