The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 68.7 for a sample of size 30 and standard deviation 9.1. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 98% confidence level). Assume the data is from a normally distributed population.

Assume that a sample is used to estimate a population mean μμ. Find the 99% confidence interval for a sample of size 1045 with a mean of 59.3 and a standard deviation of 11.6. Enter your answer as a tri-linear inequality accurate to 3 decimal places.
Assume that a sample is used to estimate a population mean μμ. Find the 80% confidence interval for a sample of size 677 with a mean of 76.8 and a standard deviation of 21.3. Enter your answer as a tri-linear 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 rounding. However, the critical value may be rounded to 3 decimal places.
