A study was conducted that measured the total brain volume (TBV) (in mm³) of patients that had schizophrenia and patients that are considered normal. The first table contains the TBV of the 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.

Transcribed Image Text:A study was conducted that measured the total brain volume (TBV) (in mm³) of patients that had
schizophrenia and patients that are considered normal. The first table contains the TBV of the 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.
