5. In a program designed to help patients stop smoking, 209 patients were given sustained care, and 82.3% of them were no longer smoking after one month. Use a 0.01 significance level to test the claim that 80% of patients stop smoking when given sustained care. Identify the null and alternative hypotheses for this test. Choose the correct answer below. OA. H₂-p=0.8 H₁: p>0.8 OB. H₂: p=0.8 H₁: p*0.8 OC. H₂:p=0.8 H₁: p<0.8 O D. H₂: p*0.8 H₁: p=0.8 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 reject the claim that 80% of patients stop smoking when given sustained care. O B. Fail to reject H. There is sufficient evidence to reject the claim that 80% of patients stop smoking when given sustained care. O C. Reject H₂. There is not sufficient evidence to reject the claim that 80% of patients stop smoking when given sustained care. OD. Reject H₂. There is sufficient evidence to reject the claim that 80% of patients stop smoking when given sustained care.
