2. (40 points) in clinical trials of the drug Lipitor, 270 subjects were given a placebo and 7 of them had an allergic reaction. Among 863 subjects treated with 10 mg of Lipitor, 18 of them experienced an allergic reaction. Construct two 95% confidence interval estimates of the percentages of allergic reactions. Show all formulas and substitutions, even if you do the work on your calculator. Compare the results. What do you conclude? Answer in complete sentences.

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...

A clinical trial was designed to compare a new drug for lowering cholesterol to a placebo. The 100 subjects who took the new drug had a mean cholesterol of 180.5 with a standard deviation of 23.3. The 100 subjects who took the placebo had a mean cholesterol of 204.1 with a standard deviation of 22.1. Construct a two-sided 95% confidence interval for the difference between the two means, assuming equal variance. Give an interpretation of the confidence interval. You MUST...

21. in a clinical trial of 2038 subjects treated with a certain drug, 22 reported headaches. In a control group of 1588 subjects given a placebo, 25 reported headaches. Denoting the proportion of headaches in the treatment group by pt and denoting the proportion of headaches in the control (placebo) group by pc, the relative risk is pt/pc. The relative risk is a measure of the strength of the effect of the drug treatment. Another such measure is the odds...
