A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 17 subjects had a mean wake time of
105.0 min. After treatment, the 17 subjects had a mean wake time of 99.2 min and a standard deviation of 22.3 min. Assume that the 17 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 with drug treatments. What
does the result suggest about the mean wake time of 105.0 min before the treatment? Does the drug appear to be effective?
Construct the 95% confidence interval estimate of the mean wake time for a population with the treatment.
min<u< min
(Round to one decimal place as needed.).
What does the result suggest about the mean wake time of 105.0 min before the treatment? Does the drug appear to be effective?
The confidence interval
the mean wake time of 105.0 min before the treatment, so the means before and after the treatment
an effect.
This result suggests that the drug treatment
