the reduction in systolic blood pressure is 46.5 for a sample of size 20 and standard deviation 14.9. 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 normally distributed population. Enter your answer as a tri-linear inequality accurate to three decimal places.
