The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the mean reduction in systolic blood pressure is 54.7 for a sample of size 1081 and standard deviation 17.6 . Estimate how much on average the drug will lower a typical patient's systolic blood pressure (using a \( 90 \% \) confidence level). a. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place. Confidence interval = b. Express the same answer as a tri-linear inequality one decimal place. c. Express the same answer using the sample mean and margin of error. Give your answers to one decimal place.

One gallon of gas is put into each of 30 test cars. The resulting gas-mileage values of the sample are computed with mean of 28.5 gallons per mile, and standard deviation of 1.2 miles per gallon. What is the \( 95 \% \) confidence interval estimate of the mean mileage? \( (28.42,28.58) \) \( (28.1,28.9) \) \( (28.46,28.54) \) \( (27.36,29.64) \) \( (27.3,29.7) \)
