Question Answered step-by-step QUESTION 13 Dr. Wendy McDonald is continuing her COVID studies… QUESTION 13Dr. 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.  Wendy McDonald would 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 obeseShe concludes that having asthma and being morbidly obese are NOT independent of each other.  Therefore, which of the following statements must be true?   P(A and O) =  P(A) x P(O)  P(A and O)  ≠  P(A) x P(O)  P(A + O) = P(A) + P(O)   P(D) = P(A) + P(O)QUESTION 14Assume a Type 1 error were made in Golestaneh’s analysis.  What could the study authors have done to try to avoid this error?  Use a lower alpha-cutoff for their P-values  Increase sample size  Better account for data loss  Use a 1-tailed instead of 2-tailed test  Link: https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(20)30199-1/fulltext Math Statistics and Probability PHS 504 Share QuestionEmailCopy link Comments (0)
