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.

Q3. A clinical trial is run to investigate the effectiveness of
an experimental drug in reducing pre-term 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 pre-term (< 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...
