QUESTION 13 Dr. Wendy McDonald is continuing her COVID studies based on Golestaneh et al. Golestaneh explores how race plays a role in COVID mortality. Many of the analyses conducted try to control for underlying comorbid factors, like pre-existing obesity or asthma. W like to perform different analysis using conditional probabilities. She defines: P(D) - probability of dying from COVID , P(A) - probability of having asthma and P(O) - probability of being morbidly obese She concludes that having asthma and being morbidly obese are NOT independent of each other. Therefore, which of the following statements must be true? O P(A and O) = P(A) x P(O) O P(A and O) # P(A) x P(O) O P(A + 0) = P(A) + P(0) O P(D) = P(A) + P(0) QUESTION 14 Assume a Type 1 error were made in Golestaneh's analysis. What could the study authors have done to try to avoid this error? O Use a lower alpha-cutoff for their P-values Increase sample size O Better account for data loss Use a 1-tailed instead of 2-tailed test QUESTION 15 Based on your knowledge of statistics and the analysis of Golestaneh et al demonstrating a "disparity in health outcomes" based on race with the Black population having the worst "Being Black is a cause of poor COVID outcomes".
