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. 160 subjects were randomly assigned to receive a placebo and 240 received the medicine. High blood pressure disappeared in 80 of the controls and in 122 of the treatment group. Test the claim that the new beta-blocker medicine is effective at a significance level of αα = 0.05. What are the correct hypotheses? H0H0: Select an answer x̅₂ σ₁ x̅₁ p μ₁ p₂ p₁ μ₂ ? ≤ ≠ < ≥ = > Select an answer μ₁ μ₂ p₁ x̅₂ 0 σ₂ p₂ x̅₁ p HaHa: Select an answer σ₁ p₂ x̅₂ p₁ x̅₁ μ₂ p μ₁ ? ≠ = < ≥ > ≤ Select an answer p₂ μ₁ p 0 μ₂ x̅₂ x̅₁ σ₁ p₁ Based on the hypotheses, find the following: Test Statistic = (Round your answer to four decimal places.) p-value = (Round your answer to four decimal places.) The test statistic is: Select an answer not in the critical region in the critical region . The correct decision is to Select an answer reject the claim fail to reject the null hypothesis accept the null hypothesis reject the null hypothesis accept the alternative hypothesis . The correct summary would be: Select an answer There is not enough evidence to reject There is enough evidence to support There is not enough evidence to support There is enough evidence to reject the claim that the new beta-blocker medicine is effective at a significance level of αα = 0.05.
