Researchers want to test to see if the recovery rate of the coronavirus is different between Mexico and Italy. They take random samples of 250 and 300 patients, from Mexico and Italy respectively. 78 of the patients from Mexico had recovered. 84 patients from Italy had recovered. Conduct a hypothesis test using a significance level of α = 0.05 to determine if there is evidence that the proportion of Mexican patients who have recovered is larger than the proportion of...
