In a program designed to help patients stop smoking. 177 patients were given sustained care, and 83.6% of them were no longer smoking after one month. Use a 0.05 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. O A. Ho: p=0.8 H:p<0.8 O B. Ho: p=0.8 H:p>0.8 OC. Hg: p#0.8 H:p= 0.8 D. Hg: p=0.8 H: p+0.8 Identify the test statistic for this hypothesis test The test statistic for this hypothesis test is 1.20 (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is O (Round to three decimal places sneeded.)
