The effectiveness of a blood-pressure drug is beinginvestigated. An experimenter finds that, on average, the reductionin systolic blood pressure is 39.5 for a sample of size 721 andstandard deviation 16.7. Estimate how much the drug will lower atypical patient's systolic blood pressure (using a 80% confidencelevel). Enter your answer as a tri-linear inequality accurate toone decimal place (because the sample statistics are reportedaccurate to one decimal place). < μ < Answer should beobtained without any preliminary rounding?
