A clinical trial was conducted to test the effectiveness of a drug used for treating insomnia in older subjects. After treatment with the drug, 16 subjects had a mean wake time of 90 min and a standard deviation of 42 8 min Assume that the 16 sample values appear to be from a normally distributed population and construct a 98% confidence interval estimate the standard deviation of the wake times for a population with the drug treatments. Does the result indicate whether the treatment is effective? Find the confidence interval estimate. min<

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. 16 subjects had a mean wake fime of 90. min and a standard deviation of 428min Assume that the 16 sample values appear to be from a normally disitibuted population and construct a 98% confidence interval estimate the standard deviation of the wake times for a population with the drug treatments. Does the result indicate whether the treatment is effective? Find the confidence interval estimate. min < σ<,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 effective because the interval does not contain 0 minutes. B. Yes, the confidence interval indicates that the treaiment is effective because the interval contains 0 minutes. C. Yes, the confidence interval indicates that the trealment is not 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 90.8 minutes. E. No, the confidence interval does not indicate whether the treatment is effective. F. Yes, the confidence interval indicates that the treatment is effective because the interval does not contain 90.8 minutes.
