2. Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6079 patients treatec with this drug, 153 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? Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: p 0.03 H1:p= 0.03 O B. Ho: p=0.03 H:p>0.03 OC. Ho: p=0.03 H;:p<0.03 O D. Ho: p=0.03 H1: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 Ho. 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. O C. Fail to reject Ho. There is not sufficient evidence to warrant rejection of the claim that 3% of users develop nausea. D D. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that 3% of users develop nausea.

Suppose 221 subjects are treated with a drug that is used to treat pain and 51 of them developed nausea. Use a 0.10 significance level to test the claim that more than 20% of users develop nausea. Identify the null and alternative hypotheses for this test. Choose the correct answer below. OA. Ho p=0.20 H₁: p 0.20 OB. Ho: p>0.20 H₁: p=0.20 C. Ho: p=0.20 H₁: p>0.20 OD. Ho p=0.20 H₁: p<0.20 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.)

A random sample of 170 donations at a certain blood bank reveals that 84 were Type A blood. Does this suggest that the actual percentage of Type A donations differs from 45%, of the population having Type A blood? A. State H0 and Ha B. Test the hypothesis using the P-Value approach at a significance level of 3%, and express your decision.  C Based on the given data, determine the extreme value without rejecting the H0.

Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 43 of the 50 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 87 of the 104 subjects developed rhinovirus infections. Use a 0.01 significance level to test the claim that echinacea has an effect on rhinovirus infections. Complete parts (a) through (c) below. a. Test the claim using a hypothesis test. Consider the first sample to be the sample of subjects treated with echinacea and the second sample to be the sample of subjects treated with a placebo. What are the null and alternative hypotheses for the hypothesis test? O A. Ho: P₁ #P2 H₁: P₁ =P₂ O D. Ho: P₁ ≤P2 H₁: P₁ P2 Identify the test statistic. Z= (Round to two decimal places as needed.) Identify the P-value. P-value= (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The P-value is the significance level of α = 0.01, so b. Test the claim by constructing an…

Suppose 214 subjects are treated with a drug that is used to treat pain and 54 of them developed nausea. Use a 0.10 significance level to test the claim that more than 20% of users develop nausea. Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: p=0.20 H₁: p>0.20 B. Ho: p=0.20 H₁: p0.20 O C. Ho: p=0.20 H₁: p0.20 H₁: p=0.20

In a study of the accuracy of fast food​ drive-through orders, one restaurant had 40 orders that were not accurate among 319 orders observed. Use a 0.05 significance level to test the claim that the rate of inaccurate orders is equal to​ 10%. Does the accuracy rate appear to be​ acceptable?

An online poll asked: "Do you believe the Loch Ness monster exists?" Among 20,926 responses, 65% were "yes." Use a 0.01 significance level to test the claim that most people believe that the Loch Ness monster exists.
