a. Let p denote the population proportion of correct hand selections by touch therapists. Identify the null and alternative hypotheses to test the claim that touch therapists use a method equivalent to random guesses. b. Identify the test statistic. c. Identify the​ P-value. d.  State the conclusion about the null​ hypothesis, as well as the final conclusion that addresses the original claim. Address whether the results suggest that touch therapists are effective.

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.)

Consider a sample of 49 football games, where 28 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: p *0.5 B. Ho: p=0.5 H₁: p 0.5 H₁: p=0.5 D. Ho: p=0.5 H₁: p>0.5 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.)

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

.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.

Assume a significance level of a 0.05 and use the given information to complete parts (a) and (b) below Original claim: The proportion of male golfers is more than 0.9 The hypothesis test results in a P-value of 0 056. a. State a conclusion about the null hypothesis. (Reject H, or fail to reject H, ) Choose the corect answer below. O A. Fal to reject H, because the P-value is less than a OB. Fal to reject H, because the P-value in greater than it OC. Reject H, because the P-value is less than a OD. Reject Hg because the P-value is greater than
