Statistics: Hypothesis Testing – #508


Question: Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value or critical values(s), conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method.

In clinical tests of the drug Lipitor, 863 patients were treated with 10 mg doses of Lipitor and 19 of those patients experienced flu symptoms. Use a 0.01 significance level to test the claim that the percentage of treated patients with flu symptoms is greater than the 1.9% rate for patients not given the treatments. Does it appear that flu symptoms are an adverse reaction of the treatment?
