The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 66.5 for a sample of size 25 and standard deviation 12.6. Estimate how much the drug will lower a typical patient’s systolic blood pressure (using a 90% confidence level). Assume the data is from a normal distributed population. Enter your answer as a tri-liner inequality accurate to three decimal places.
