Assume that the probability of having sickle cell anemia is 0.15 and the probability of being African-American is 0.45 in a given population. Additionally, assume the joint probability of having sickle cell anemia and being African-American in this population is 0.13. A) What is the probability of having sickle cell anemia, given that you are African-American in this given population? B) Suppose we know that the probability of having sickle cell anemia, given that you are Asian-American is 0.21. What can we say about the relative risk of sickle cell anemia in African-Americans versus Asian Americans? Interpret this result.
