9.3.4 A study was conducted that measured the total brain volume (TBV) (in m3) of patients that had schizophrenia and patients that are considered normal. Table #935 contains the TBV of the normal patients and table #9.3.6 contains the TBV of schizophrenia patients {"SOCR data oct2009," 2013). Compute a 90% condence interval for the difference in TBV of normal patients and patients with Schizophrenia.
