Assume a significance level of a = 0.05 and use the given information to complete parts (a) and (b) below. Original claim: More than 54% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.21 a. State a conclusion about the null hypothesis. (Reject Ho or fail to reject Ho.) Choose the correct answer below. O A. Reject Ho because the P-value is greater than a. OB. Reject Ho because the P-value is less than or equal to a. OC. Fail to reject Ho because the P-value is less than or equal to a. OD. Fail to reject Ho because the P-value is greater than a.

Consider a sample of 54 football games, where 30 of them were won by the home team. Use a 0.10 significance level to test the claim that the probability that the home team wins is greater than one-half. Identify the null and alternative hypotheses for this test. Choose the correct answer below. OA. Ho: p=0.5 H₁: p0.5 OC. Ho: p>0.5 H₁: p=0.5 OD. Ho: p=0.5 H₁: p 0.5 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is 0.82. (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.)

The p-value for a hypothesis test turns out to be 0.0985. At a 8% level of significance, what is the proper decision? Reject H0H0 Fail to reject H0

Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6167 patients treated with this drug, 150 developed the adverse reaction of nausea. Use a 010 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 H, p=003 O B. H, p=0.03 H p0.03

An online poll​ asked: "Do you believe the Loch Ness monster​ exists?" Among 22185 responses, ​69%were​ "yes." Use a 0.10 significance level to test the claim that most people believe that the Loch Ness monster exists. How is the conclusion affected by the fact that Internet users who saw the question could decide whether to​ respond? Identify the null and alternative hypotheses for this test. Choose the correct answer below.     A. H0​: p>0.5 H1​: p=0.5   B. H0​: p=0.5 H1​: p<0.5   C. H0​: p=0.5 H1​: p>0.5   D. H0​: p=0.5 H1​: p≠0.5 Part 2 Identify the test statistic for this hypothesis test.   The test statistic for this hypothesis test is enter your response here. ​(Round to two decimal places as​ needed.) Part 3 Identify the​ P-value for this hypothesis test.   The​ P-value for this hypothesis test is enter your response here. ​(Round to three decimal places as​ needed.) Part 4 Identify the conclusion for this hypothesis test.…

Consider a drug testing company that provides a test for marijuana usage. Among 266 tested subjects, results from 27 subjects were wrong (either a false positive or a false negative). Use a 0.05 significance level to test the claim that less than 10 percent of the test results are wrong. Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: p0.1 O C. Ho: p= 0.1 H: p#0.1 O D. Ho: p=0.1 H:p<0.1 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. Fail to reject Ho. There is sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. O B. Reject Ho. There is sufficient evidence to warrant support of the claim that less than…

Q13. The null Hypothesis is rejected, if the P-value is larger than significance level.a. Trueb. False

After performing a hypothesis test, the p-value is p = 0.013. If the test was performed at a significance level of a = 0.046, should the null hypothesis be rejected? O a. Reject the null hypothesis since 0.013 0.046 O c. Reject the null hypothesis since 0.013 > 0.046 O d. Fail to reject the null hypothesis since 0.013 < 0.046

Use the random sample data to test the claim that 72% of students have internet access at home.  Use 5% level of significance. Sample data:  x = 158, n = 200 1. Identify the tail of the test. 2.Find the P-value                                  3.Will the null hypothesis be rejected?                          4. Is the initial claim supported?

.2.3 Assigned Media The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a = 0.01, (b) a = 0.05, and (c) a= 0.10. P=0.0618 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? A. Reject Ho because the P-value, 0.0618, is greater than a= 0.01. B. Reject Ho because the P-value, 0.0618, is less than a =0.01. C. Fail to reject Ho because the P-value, 0.0618, is less than oa= 0.01. O D. Fail to reject Ho because the P-value, 0.0618, is greater than a= 0.01.
