Aclinical trial was conducted to test the effectiveness of the drug zopiclone for treating insomnia in older subjects. before treatment with zopiclone, 16 subjects had a mean wake time of 103.0 minutes. after treatment with zopiclone, the 16 subjects had a mean wake time of 81.4 minutes and s standard deviation of 24.3 minutes. assume that the 16 sample values appear to be from a normally distributed population and construct a 90% confidence interval estimate of the mean wake time for a population with zopiclone treatments. what does the result suggest about the mean wake time of 103.0 minutes before the treatment? does zopiclone appear to be effective?
construct the 90? % confidence interval estimate of the mean wake time for a population with the treatment

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining bismuth-210 transforms into another atom (polonium-210 in this case) each day. if you begin with 233 mg of bismuth-210, how much remains after 8 days?
