The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, for a sample of 27 patients taking the drug, the mean reduction in systolic blood pressure is 55.8 mmHg (millimeters of mercury) with a sample standard deviation 9.9 mmHg. Compute a 99% confidence interval for the population mean to determine how much blood pressure will be reduced for a typical patient after taking the drug? a. Is n > 30 ? Yes O No b. Confidence Interval: What is the 99% confidence interval to estimate the population mean? Round your answer to one decimal place. ANSWER: We can say with 99% confidence that the true population mean reduction in blood pressure lies in the interval millimeters of mercury
