1.Consider a drug that is used to help prevent blood clots in certain patients. In clinicaltrials, among 6196 patients treated with thisdrug, 163 developed the adverse reaction of nausea. Use a 0.10 significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic adversereaction?

a. Identify the test statistic for this hypothesis test.

The test statistic for this hypothesis test is (Round to two decimal places asneeded.

b. dentify theP-value for this hypothesis test.

TheP-value for this hypothesis test is (Round to three decimal places asneeded.

2.Suppose 225 subjects are treated with a drug that is used to treat pain and 54 of them developed nausea. Use a 0.01 significance level to test the claim that more than 20% of users develop nausea.

a.The test statistic for this hypothesis test is (Round to two decimal places asneeded.

b. TheP-value for this hypothesis test is (Round to three decimal places asneeded.

3.In a study of 786 randomly selected medical malpracticelawsuits, it was found that 481 of them were dropped or dismissed. Use a 0.05 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed.

a.What is the teststatistic?

z= (Round to two decimal places asneeded.)

b.What is theP-value?

P-value= (Round to three decimal places asneeded.)
