A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 22 subjects had a mean wake time of 104.0 min. After treatment, the 22 subjects had a mean wake time of 97.1 min and a standard deviation of 21.5 min. Assume that the 22 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 tim 104.0 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. O min

Question

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.

**Study of Drug Effectiveness on Insomnia in Older Subjects** A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 22 subjects had a mean wake time of 104.0 minutes. After treatment, the 22 subjects had a mean wake time of 97.1 minutes with a standard deviation of 21.5 minutes. The trial assumes that the 22 sample values come from a normally distributed population. The objective is to construct a 95% confidence interval estimate of the mean wake time for a population treated with the drug. The primary question is whether this drug significantly reduces the mean wake time from the initial 104.0 minutes. Does the drug appear to be effective? **Confidence Interval Construction** To find out, the 95% confidence interval estimate of the mean wake time for the treated population needs to be calculated. Please provide the interval in the following format: \[ \text{min} < \mu < \text{min} \] *Round to one decimal place as needed.*
