W5Q9

The 2nd part is about completing a sentence, plase provide an answer and a short explanation for all the parts of the exercise.

What does the result suggest about the mean wake time of 104.0 min before the​ treatment? Does the drug appear to be​ effective?

The confidence interval (Includes / Does not include) the mean wake time of 104.0 min before the​ treatment, so the means before and after the treatment (Are different / Could be the same) This result suggests that the drug treatment (Has / Does not have ) a significant effect.

A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 21 subjects had a mean wake time of 100.0 min. After treatment, the 21 subjects had a mean wake time of 90.1 min and a standard deviation of 23.9 min. Assume that the 21 sample values appear to be from a normally distributed population and construct a 99% 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 100.0 min before the treatment? Does the drug appear to be effective?

Construct the 99% confidence interval estimate of the mean wake time for a population with the treatment.

[ ] min ≤ μ < [ ] min

(Round to one decimal place as needed.)
