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 290 received the medicine. High blood pressure disappeared in 80 of the controls and in 159 of the treatment group. Test the claim that the new beta-blocker medicine is effective at a significance level of a = 0.01. What are the correct hypotheses? H0: p1 = p2 H1: p1< p2 Based on the hypotheses, find the following: Test Statistic = ? p-value = ? The test statistic is: not critical to the region The correct decision is to fail to reject the null hypothesis The correct summary would be: there is not enough evidence to support the claim that the new beta-blocker medicine is effective at a significance level of a = 0.01.

What are the correct hypotheses?
H0: p1 = p2
H1: p1< p2
Based on the hypotheses, find the following:
Test Statistic = ?
p-value = ?
The test statistic is: not critical to the region
The correct decision is to fail to reject the null hypothesis
The correct summary would be: there is not enough evidence to support the claim that the new beta-blocker medicine is effective at a significance level of a = 0.01.
