Question

The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction
in systolic blood pressure is 16.4 for a sample of size 26 and standard deviation 5.2. Estimate how much the drug will
lower a typical patient's systolic blood pressure (using a 98% confidence level). Assume the data is from a normally
distributed population.
Enter your answer as a tri-linear inequality accurate to three decimal places.
