paper in the Journal of Nervous and Mental Disorders reported the following data on the amount of dextroamphetamine excreted by a sample of children having organically related disorders and a sample of children with nonorganic disorders (dextroamphetamine is a drug commonly used to treat hyperkinetic children). Organic: 17.53, 20.60, 17.62, 28.93, 27.10 Nonorganic: 15.59, 14.76, 13.32, 12.45, 12.79 (Observations refer to percentage of recovery of the drug seven hours after its administration.) If we assume that the variances of the two groups of children are unequal, determine whether the true average percentages of recovery for the two conditions are equal at significance level 0.01
