A standard drug is known to be effective in 74 percent of cases in which it is used to treat a certain infection. A new drug has been developed, and testing has found it to be effective in 112 cases out of 187. Scientists want to know if the data show enough evidence to prove that there are differences in the effectiveness rates between two drugs. 1. Choose a suitable alternative hypothesis. H1: Select an answer 2. Find the test statistic: Select an answer 3. Hence, we conclude that at the a = 0.05 level of significance, Select an answer Select an answer we have a strong evidence to confirm that there are differences in the effectiveness rates between two drugs. we do not have enough evidence to confirm that there are differences in the effectiveness rates between two drugs.
