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. 180 subjects were randomly assigned to receive a placebo and 220 received the medicine. High blood pressure disappeared in 80 of the controls and in 118 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? H0: Select an answer x̅₂ p x̅₁ μ₂ p₁ μ₁ σ₁ p₂ ? ≥ < ≤ = ≠ > Select an answer 0 σ₂ μ₂ μ₁ x̅₂ p₁ p p₂ x̅₁ H1: Select an answer p p₁ σ₁ x̅₁ μ₁ x̅₂ μ₂ p₂ ? = ≥ ≤ ≠ > < Select an answer μ₁ p₁ p x̅₂ μ₂ p₂ 0 x̅₁ σ₁ Based on the hypotheses, find the following: Test Statistic = p-value = The test statistic is: Select an answer in the critical region not in the critical region . The correct decision is to Select an answer accept the alternative hypothesis reject the claim fail to reject the null hypothesis accept the null hypothesis reject the null hypothesis . The correct summary would be: Select an answer There is not enough evidence to support There is not enough evidence to reject There is 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.

What are the correct hypotheses?
H0: Select an answer x̅₂ p x̅₁ μ₂ p₁ μ₁ σ₁ p₂ ? ≥ < ≤ = ≠ > Select an answer 0 σ₂ μ₂ μ₁ x̅₂ p₁ p p₂ x̅₁
H1: Select an answer p p₁ σ₁ x̅₁ μ₁ x̅₂ μ₂ p₂ ? = ≥ ≤ ≠ > < Select an answer μ₁ p₁ p x̅₂ μ₂ p₂ 0 x̅₁ σ₁
Based on the hypotheses, find the following:
Test Statistic =
p-value =
The test statistic is: Select an answer in the critical region not in the critical region .
The correct decision is to Select an answer accept the alternative hypothesis reject the claim fail to reject the null hypothesis accept the null hypothesis reject the null hypothesis .
