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 230 received the medicine. High blood pressure disappeared in 100 of the controls and in 146 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? O pa H1: p: p: Based on the hypotheses, find the following: Test Statistic = p-value =

One study claimed that 88 % of college students identify themselves as procrastinators. A professor believes that the claim regarding college students is too high. The professor conducts a simple random sample of 272 college students and finds that 231 of them identify themselves as procrastinators. Does this evidence support the professor's claim that fewer than 88 % of college students are procrastinators? Use a 0.02 level of significance. Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. Ho p = 0.88 Ha P 0.88
A researcher wants to know if mood is affected by music. She conducts a test on a sample of 4 randomly selected adults and measures mood rating before and after being exposed to classic rock music. Test the hypothesis that mood rating decreased after being exposed to classic rock music. The mood ratings for the four participants are provided. Assume that all conditions for testing have been met. Report the null and alternative hypothesis and p-value. At the 1% significance level, state the decision regarding the null hypothesis and the conclusion about the original claim. Round all values to the nearest thousandth. Click the icon to view the mood ratings. OA. Ho Hdifference =0, Ha Hdifference >0; p=0.373; Reject the null hypothesis; there is strong evidence to suggest that exposure to classic rock music decreased mood rating. B. Ho Hdifference =0, Ha Hdifference >0; p=0.373; Fail to reject the null hypothesis; there is not strong evidence to suggest that exposure to classic rock music…
