A very large study showed that aspirin reduced the rate of first heart attacks by %. A pharmaceutical company thinks they have a drug that will be more effective than aspirin, and plans to do a randomized clinical trial to test the new drug. What is the null hypothesis the company will use?.

the null hypothesisthe company will use p =0.44.z test?z testcan be used to determine whether themeansof two populations differ from one another. Thez teststatistic’svalue must be determined, together with the null hypothesis and alternativehypothesissetups, for this reason. On thezcriticalvalue, the decision criterion is based. Thedistributiongraph is divided into acceptance andrejectionzones during hypothesis testing by the z critical value. Thenull hypothesiscan be rejected if the test statistic lies inside therejectionregion; otherwise, it cannot.distributedand using the sample mean.hypothesisthe company will use p =0.44.z test, by the following link.
