The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 30 for a sample of size 11 and standard deviation 8. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 98% confidence level). Give your answers to one decimal place and provide the point estimate with its margin of error. +
