A new beta-blocker medication is being tested to treat high blood pressure. Subjects with high blood pressure volunteered to take part in the experiment. 170 subjects were randomly assigned to receive a placebo and 290 received the medicine. High blood pressure disappeared in 80 of the controls and in 167 of the treatment group. Test the claim that the new beta-blocker medicine is effective at a significance level of α = 0.01. 1) What are the correct hypotheses? H0: H1: 2) Based on the hypotheses, find the following: Test Statistic = p-value = 3) The correct summary would be: the claim that the new beta-blocker medicine is effective at a significance level of α = 0.01. (Note: Z and T tables will be incorrect for this course)
