Question no. 1
A study was conducted that measured the total brain volume (TBV) (in ) of patients that had schizophrenia and patients that are 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 data oct2009," 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.
Question no. 2
A study was conducted that measured the total brain volume (TBV) (in ) of patients that had schizophrenia and patients that are 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 data oct2009," 2013).Compute a 90% confidence interval for the difference in TBV of normal patients and patients with Schizophrenia.
