A clinical trial is run to investigate the effectiveness of an experimental drug in reducing preterm delivery to a drug considered standard care and to placebo. Pregnant women are enrolled and randomly assigned to receive either the experimental drug, the standard drug or placebo. Women are followed through delivery and classified as delivering preterm (< 37 weeks) or not. The data are shown below.

A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before​ treatment, 18 subjects had a mean wake time of 103.0 min. After​ treatment, the 18 subjects had a mean wake time of 78.4 min and a standard deviation of 20.7 min. Assume that the 18 sample values appear to be from a normally distributed population and construct a 95 ​% confidence interval estimate of the mean wake time for a population...
