Question: Assume that a simple random sample is taken from a normally distributed population. Identify the 1) null hypothesis (Ho), 2) the alternative hypothesis (H1),3) the test statistic, 4) the critical value(s) 5) the p-value, 6) the conclusion about the null hypothesis (reject or fail to reject), and 7) draw a sketch of the appropriate distribution, with the critical value, critical region, and test statistic marked, and 7) write a final conclusion that addresses the initial claim.

In clinical trials of the drug Lipitor 942 patients were treated with 10 ml doses of the drug and 21 of those patients experienced flu symptoms. Use a .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 treatment.
