An experimenter finds that, on average, the reduction in systolic blood pressure is 80.1 for a sample of size 643 and standard deviation 5.4. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 98% 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). 79.605 voWe wish to estimate what percent of adult residents in a certain county are parents.
