In a program designed to help patients stop smoking, 181 patients were given sustained care, and 80.7% 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. OA. Ho: p*0.8 H₁: p=0.8 OB. Ho: p=0.8 H₁: p>0.8 OC. Ho: p=0.8 H₁: p*0.8 OD. Ho: 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. OA. Fail to reject Ho. There is sufficient evidence to reject the claim that 80% of patients stop smoking when given sustained care. OB. Reject Ho. There is not sufficient evidence to reject the claim that 80% of patients stop smoking when given sustained care. OC. Fail to reject Ho. There is not sufficient evidence to reject the claim that 80% of patients stop smoking when given sustained care. OD. Reject Ho. There is sufficient evidence to reject the claim that 80% of patients stop smoking when given sustained care.

Question
Transcribed Image Text:In a program designed to help patients stop smoking, 181 patients were given sustained care, and 80.7% 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
H₁: p=0.8
OB. Ho: p=0.8
H₁: p>0.8
OC. Ho: p=0.8
H₁: p *0.8
D. Ho: 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.
C
O A. Fail to reject Ho. There is sufficient evidence to reject the claim that 80% of patients stop smoking when given sustained care.
O B. Reject Ho. There is not sufficient evidence to reject the claim that 80% of patients stop smoking when given sustained care.
O C. Fail to reject Ho. There is not sufficient evidence to reject the claim that 80% of patients stop smoking when given sustained care.
O D. Reject Ho. There is sufficient evidence to reject the claim that 80% of patients stop smoking when given sustained care.
