Consider a sample of 47 football games, where 28 of them were won by the home team. Use a 0.01 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. O A. Ho: p=0.5 H₁: p=0.5 ⒸB. Ho: p=0.5 H₁: p>0.5 O C. Ho:p>0.5 H₁: p=0.5 O 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.) 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 not sufficient evidence to support the claim that the probability of the home team winning is greater than one-half. B. Reject Ho. There is not sufficient evidence to support the claim that the probability of the home team winning is greater than…
