The drug Lipitor is meant to reduce total cholesterol and LDL cholesterol. In clinical trials, 19 out of 863 patients taking 10 mg of Lipitor daily complained of flu-like symptoms. Suppose that it is known that 1.9% of patients taking competing drugs complain of flu-like symptoms. Is there sufficient evidence to support the claim that more than 1.9% of Lipitor users experience flu-like symptoms as a side effect?
I think I am supposed to use the hypothesis test on this one..? Any help would be appreciated!
