The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 73.1 for a sample of size 29 and standard deviation 16.5. Estimate how
much the drug will lower a typical patient's systolic blood pressure (using a 99% confidence level). Assume the
data is from a normally distributed population.
Enter your answer as a tri-linear inequality accurate to three decimal places.
