study was conducted that measured the total brain volume (TBV) (in mm³) of patients that had chizophrenia and patients that are considered normal. The first table contains the TBV of the non- chizophrenic patients and the second table contains the TBV of schizophrenia patients. Compute a 99% onfidence interval for the difference in TBV of non-schizophrenic patients and patients with chizophrenia. Prior studies say nothing about the equality of variances.
