- The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 67.2 for a sample of size 27 and standard deviation 13.9. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 99% confidence level). Assume the data is from a normally distributed population. Enter your answer as a tri-linear inequality accurate to three decimal places.Assume that a sample is used to estimate a population proportion p. Find the 99.9% confidence interval for a sample of size 269 with 52% successes.
