Suppose 215 subjects are treated with a drug that is used to treat pain and 50 of them developed nausea. Use a 0.10 significance level to test the claim that more than 20% of users develop nausea. Identify the null and alternative hypotheses for this test. Choose the correct answer below. OA. Ho: p=0.20 H₁: p<0.20 OB. Ho: p=0.20 H₁: p=0.20 OC. Ho:p>0.20 H₁: p=0.20 O D. Ho: p=0.20 H₁: p>0.20 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. Reject Ho. There is not sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. OB. Fail to reject Ho. There is not sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. OC. Fail to reject Ho. There is sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. OD. Reject Ho. There is sufficient evidence to warrant support of the claim that more than 20% of users develop nausea.

Question
Suppose 215 subjects are treated with a drug that is used to treat pain and 50 of them developed nausea. Use a 0.10 significance level to test the claim that more than 20% of users develop nausea.
Identify the null and alternative hypotheses for this test. Choose the correct answer below.
O A. Ho: p=0.20
H₁: p<0.20
OB. Ho: p=0.20
H₁: p=0.20
O C. Ho:p>0.20
H₁: p=0.20
O D. Ho: p=0.20
H₁: p>0.20
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. Reject Ho. There is not sufficient evidence to warrant support of the claim that more than 20% of users develop nausea.
O B. Fail to reject Ho. There is not sufficient evidence to warrant support of the claim that more than 20% of users develop nausea.
O C. Fail to reject Ho. There is sufficient evidence to warrant support of the claim that more than 20% of users develop nausea.
