Question
A study was conducted that measured the total brain volume (TBV) in mm³ of patients with schizophrenia and those considered normal. The first table displays the TBV of non-schizophrenic patients, and the second table shows the TBV of schizophrenia patients. The task is to compute a 95% confidence interval for the difference in TBV between non-schizophrenic patients and those with schizophrenia. Prior studies say nothing about the equality of variances. Round to the nearest whole number. **Total Brain Volume (in mm³) of Non-Schizophrenic Patients:** | | | | | | | |------|------|------|------|------|------| | 1493670 | 1505354 | 1642063 | 1269967 | 1520437 | 1581952 | | 1549683 | 1338983 | 1422347 | 1492283 | 1195153 | 1396509 | | 1485412 | 1618109 | 1459455 | 1717233 | 1357073 | 1576932 | | 1548420 | 1484842 | 1595374 | 1679448 | 1569374 | 1370347 | | 1396599 | 1533894 | 1565016 | 1340012 | 1478392 | 1417992 | | 1550295 | 1478392 | 1389635 | | | | **Total Brain Volume (in mm³) of Schizophrenia Patients:** | | | | | | | |------|------|------|------|------|------| | 1274453 | 1212643 | 1523072 | 1543675 | 1466250 | 1299458 | | 1592091 | 1730346 | 1074105 | 1362385 | 1435833 | 1603966 | | 1248181 | 1424469 | 1254952 | 1714717 | 1394137 | 1504040 | | 1535391 | 1358897 | 1236700 | 1369520 | 1387450 | 1679837 | | 1662816 | 126922
