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.
