Extracted text: The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 84.4 for a sample of size 1013 and standard deviation 7.4. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 95% confidence level). Enter your answer as an inequality accurate to one decimal place (because the sample statistics are reported accurate to one decimal place). < µ="">< answer="" should="" be="" obtained="" without="" any="" preliminary="">
