Study was conducted that measured the total brain volume (TBV) (in mm3) of patients that had schizophrenia and patients that ate considered normal. Table #9.3.5 contains the TBV of the normal patients and Table #9.3.6 contains the TBV of Schizophrenia patients ( "SOCR date oct, "2013). Compute a 90% confidence interval for the difference in TBV of normal patients and patients with Schizophrenia.
