Question

Suppose 230 subjects are treated with a drug that is used to treat pain and 50 of them developed nausea. Use a 0.05 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.

A. Upper H 0H0​: p=0.20

Upper H1​: pl<0.20

B. Upper H0​: p=0.20

Upper H1​: p>0.20

C. Upper H0​: p=0.20

Upper H1​: p≠0.20

D. Upper H0​: p>0.20

Upper HH1​: 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.

A.Fail to reject Upper H 0H0. There is sufficient evidence to warrant the support of the claim that more than 20​% of users develop nausea.

B.Reject Upper H 0H0. There is not sufficient evidence to warrant support of the claim that more than 20​% of users develop nausea.

C. Fail to reject Upper H0. There is not sufficient evidence to warrant the support of the claim that more than 20%of users develop nausea.

D. RejectUpper H0.There is sufficient evidence to warrant the support of the claim that more than 20​%of users develop nausea.
