  1. Using a test of independent/association:
    1. Test if smoking status is independent of sex at birth.
    2. Test if diabetes diagnosis is independent of sex at birth.
    3. Test if cancer diagnosis is independent of relationship type.
    4. Test if sex at birth is independent of relationship type.
  2. Calculate the effect size for each test.
