A study was conducted that measured the total brain volume {TBV} (in mm\") 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 TB'i:r of schizophrenia patients (\"SOCR data oct2099," 2013). Is there enough evidence to show that the patients with schizophrenia have less TBV on average than a patient that is considered normal? Test at the 10% level
