The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 44.4 for a sample of size 1016 and standard deviation 5.1. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 99% 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). <μ<

Expert Solution
Step 1

Given information

Sample size (n) = 1016

Sample mean = 44.4

Standard deviation (s) = 5.1

Significance level (α) = 1 - 0.99 = 0.01

Since, here population standard deviation is unknown and sample size is very large therefore using t-distribution.
