Consider a drug that is used to help prevent blood clots in certain patients. In clinical​ trials, among 6267 patients treated with this​ drug, 168 developed the adverse reaction of nausea. Use a 0.05 significance level to test the claim that 3​% of users develop nausea. Does nausea appear to be a problematic adverse​ reaction?

Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6225 patients treated with this drug, 164 developed the adverse reaction of nausea. Use a 0.01 significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic adverse reaction? OC. Ho:p= 0.03 H4:p>0.03 O D. Ho: p#0.03 H:p=0.03 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is. (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Reject Hn. There is sufficient evidence to warrant rejection of the claim that 3% of users develop nausea. O B. Reject Ho. There is not sufficient evidence to warrant rejection of the claim that 3% of users develop nausea. OC. Fail to reject Ho. There is sufficient evidence to warrant rejection…

A researcher gathered a sample of participants who volunteered for a studying of phobias. She measured anxiety level of participants as they viewed photos of spiders and again when they viewed puppies. Which statistical test is appropriate for this study and why?

During the 1990s, the fatality rate for lung cancer was 80 per 100,000 people. After the turn of the century and the establishment of newer treatments and adjustment in public health advertising, a random sample of 10,000 people exhibits only six deaths due to lung cancer. Test at the 0.05 significance level whether that data are proof of a reduced fatality rate for lung cancer. b. Make the decision rule. (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.)  c. Evaluate the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.)
