A simple random sample of 16 subjects with the treatment of zopiclone had a mean wake time of 102.8 min. After treatment with zopiclone, the 16 subjects had a mean wake time of 98.9 min and a standard deviation of 42.3 min. Use a 0.05 significance level to claim that after treatment with zopiclone, subjects had a mean waketime less than 102.8 min.
