The effectiveness of a blood-pressure drug is being
investigated. An experimenter finds that, on average, the reduction
in systolic blood pressure is 83.2 for a sample of size 1068 and
standard deviation 7.7.
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).
