The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 81.8 for a sample of size 458 and standard deviation 14.9. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 99% confidence level).
