Suppose 220 subjects are treated with a drug that is used to treat pain and 54 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.
A.
Upper H 0?: p equals 0.20
Upper H 1?: p not equals 0.20
B.
Upper H 0?: p equals 0.20
Upper H 1?: p greater than 0.20
C.
Upper H 0?: p greater than 0.20
Upper H 1?: p equals 0.20
D.
Upper H 0?: p equals 0.20
Upper H 1?: p less than 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 conclusion for this hypothesis test.
A.
Reject Upper H 0. There is sufficient evidence to warrant support of the claim that more than 20?% of users develop nausea.
B.
Fail to reject Upper H 0. There is sufficient evidence to warrant support of the claim that more than 20?% of users develop nausea.
C.
Reject Upper H 0. There is not sufficient evidence to warrant support of the claim that more than 20?% of users develop nausea.
D.
Fail to reject Upper H 0. There is not sufficient evidence to warrant support of the claim that more than 20?% of users develop nausea.
