25. Lipitor In clinical trials of the drug Lipitor (atorvastatin), 270 subjects were given a pla- cebo and 7 of them had allergic reactions. Among 863 subjects treated with 10 mg of the drug, 8 experienced allergic reactions. Construct the two 95% confidence interval estimates of the percentages of allergic reactions. Compare the results. What do you conclude?
