Question

Suppose 218subjects are treated with a drug that is used to treat pain and 51 of them developed nausea. Use a 0.01 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 H0​: p=0.20

Upper H1​: p>0.20

B.

Upper H 0: p>0.20

Upper H1​: p=0.20

C.

Upper H 0H0​: p= 0.20

Upper H 1H1​: p<0.20

D. Upper H0​: p=0.20

Upper 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.

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

B. Reject Upper H0. 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 support of the claim that more than 20​% of users develop nausea.

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