According to the University of Chicago, as men age, their cholesterol level goes up. A new drug (XAB) is being tested to determine if it can lower cholesterol in aging males and at what dose. The data for the first test subject is below:
Dose (mg): 2 3 5 6 8 10
Cholesterol level (mg/dL): 310 124 190 110 52 20
- Plot the data with a regression line and perform a regression with the appropriate statistical test in StatCrunch. Copy and paste your graph and regression output into your Word document for full credit. What is the correlation coefficient r,and what is the coefficient of determination here? What does the coefficient of determination mean in this case? Is there a statistically significant correlation between the dose and cholesterol in this sample? What hypotheses did you test? Using StatCrunch, what is the predictedcholesterol level for a person taking a dose of 7 mg?
