Find the confidence interval estimate. 32.48 min << 72.17 min (Round to two decimal places as needed.) Does the result indicate whether the treatment is effective? A. Yes, the confidence interval indicates that the treatment is not effective because the interval does not contain 97.7 minutes. OB. Yes, the confidence interval indicates that the treatment is not effective because the interval contains 0 minutes. OC. Yes, the confidence interval indicates that the treatment is effective because the interval contains 0 minutes. D. Yes, the confidence interval indicates that the treatment is not effective because the interval does not contain 0 minutes OE. Yes, the confidence interval indicates that the treatment is effective because the interval does not contain 0 minutes. OF. No, the confidence interval does not indicate whether the treatment is effective. O G. Yes, the confidence interval indicates that the treatment is effective because the interval does not contain 97.7 minutes.

Question
![A clinical trial was conducted to test the effectiveness of a drug used for treating insomnia in older subjects. After treatment with the drug, 14 subjects had a mean wake time of 97.7 min and a standard deviation of 44.8 min. Assume that the 14 sample values appear to be from a normally distributed
population and construct a 95% confidence interval estimate of the standard deviation of the wake times for a population with the drug treatments. Does the result indicate whether the treatment s effective?
