Question

The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 76.4 for a sample of size 698 and standard deviation 9.9.

Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 90% confidence level).

Enter your answer as a tri-linear inequality accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).

 < μ <  

Answer should be obtained without any preliminary rounding.
