Information Refer to the following information: Mancia et al. (2020) conducted a case-control study in the Lombardy region of Italy to examine the association between the use of angiotensin-converting-enzyme (ACE) inhibitors and the odds of coronavirus disease 2019 (COVID-19). There were 1,502 COVID-19 cases among the 8,071 patients who used ACE inhibitors. There were 4,770 COVID-19 cases among the 28,960 patients who did not use ACE inhibitors. Using a 0.05 significance level, you need to test the claim that the proportion of COVID-19 patients among those who used ACE inhibitors (group 1) is higher than the proportion of COVID-19 patients among those who did not use ACE inhibitors (group 2). To do so, answer each of the following questions. Q 13 What proportion of ACE inhibitor users were not COVID-19 cases? Select one: O a. 0.14 O b. 0.16 O c. 0.19 O d. 0.81 O e. 0.84 Q 14 What is the null hypothesis Ho? Select one: O a. P1 = P2 O b. P1 * P2 O c. P12 P2 O d. P1
