The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 24.9 mmHg (millimeters of mercury) for a sample of size 18 and a sample standard deviation 9.6 mmHg. How much of mmHg will lower for a typical patient's systolic blood pressure after taking the drug? Estimate with a 90% confidence. Preliminary: Is n > 30? O Yes No
