A clinical trial was conducted to test the effectiveness of a drug testing for insomnia and older subjects before the treatment 25 subjects had a mean wake up time at 102 minutes after the treatment 25 subjects that had a mean of 75.1 minutes and a standard deviation of 21.2 minutes assume the 25 sample values appear to be normally distributed and construct a 99% confidence interval estimate of the main wake up time for a population with drug treatments what does the results suggest about the mean wake up time of 102 minutes before the treatment does the drug appear to be effective
