The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 41 for a sample of size 20 and standard deviation 12. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 95% confidence level). Give your answers to one decimal place and provide the point estimate with its margin of error.
