1.You want to design an intervention that will help improve CD4 counts among people living with HIV and suspect there may be differences at baseline by gender ( but need to run an analysis to see if this assumption is correct. Dependent variable = CD4; independent variable = Gender.

a.Which type of statistical test would you use to answer this question (independent, multiple, or pairwise comparison)? (5 points)

b.Run the appropriate data checks to determine which specific test you should use - explain which test you chose and why. (10 points)

c.Run the statistical test chosen in part b and provide an interpretation of your findings reporting statistical findings (e.g. What is mean and SD of CD4 count for female, male, and transgender? Are there gender differences in mean CD4 count at baseline?). (19 points)
