The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 58.9 for a sample of size 910 and standard deviation 18.1. 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 58.9 for a sample of size 910 and standard
deviation 18.1.
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).
Answer should be obtained without any preliminary rounding.
