The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 66.2 for a sample of size 902 and standard deviation 10.5. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 95% 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).

Question
The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average,
the reduction in systolic blood pressure is 66.2 for a sample of size 902 and standard deviation 10.5.
Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 95% 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).
