Transcribed Image Text:The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on
average, the reduction in systolic blood pressure is 28.8 for a sample of size 697 and standard
deviation 20.4.
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).
Answer should be obtained without any preliminary rounding.
