A researcher hypothesizes that obesity is associated with an inflammatory profile. He collects a sample of 24 obese individuals (i.e., BMI > 30) drawn for the hospital population to compare the inflammatory marker, C reactive protein (CRP), with that of the regular patient population. The population had a mean CRP of 5.6 mg/L and a standard deviation of 2.4 mg/L. And the sample mean was 81.5 mg/dL. Assume CRP is normally distributed. Which statistical analysis are you going to use for testing this research question?

• A. Chi-square test
• B. ANOVA
• C. One sample T-test
• D. Independent sample T-test
