Question
Transcribed Image Text:A study was conducted that measured the total brain volume (TBV) (in mm³) of patients with schizophrenia and patients considered normal. The first table contains the TBV of non-schizophrenic patients, and the second table contains the TBV of schizophrenia patients. Compute a 99% confidence interval for the difference in TBV of non-schizophrenic patients and patients with schizophrenia. Prior studies say nothing about the equality of variances. Round to the nearest whole number.
