Before treatment, 13 subjects had a mean wake time of 101.0 min. After treatment, the 13 subjects had a mean wake time of 92.2 min and a standard deviation of 20.4 min. Assume that the 13 sample values appear to be from a normally distributed population and construct a 99% confidence interval estimate of the mean wake time for a population with drug treatments. What does the result suggest about the mean wake time of 101.0 min before the treatment? Does the drug appear to be effective? Construct the 99% confidence interval estimate of the mean wake time for a population with the treatment. min <>< min="" (round="" to="" one="" decimal="" place="" as="" needed.)="" what="" does="" the="" result="" suggest="" about="" the="" mean="" wake="" time="" of="" 101.0="" min="" before="" the="" treatment?="" does="" the="" drug="" appear="" to="" be="" effective?="" the="" confidence="" interval="" the="" mean="" wake="" time="" of="" 101.0="" min="" before="" the="" treatment,="" so="" the="" means="" before="" and="" after="" the="" treatment="" this="" result="" suggests="" that="" the="" drug="" treatment="" va="" significant="" effect.="" enter="" your="" answer="" in="" each="" of="" the="" answer="" boxes.="" que="" all="" p="" p="" type="" here="" to="" search="">
