U Question 8 3 pts Lipitor (atorvastatin) is a drug used to control cholesterol. In clinical trials of Lipitor, 94 subjects were treated with Lipitor and 270 subjects were given a placebo. Among those treated with Lipitor, 7 developed infections. Among those given a placebo, 27 developed infection. We want to use a 0.05 significance level to test the claim that the rate of infections was the same for those treated with Lipitor as those given a placebo. A What...
