A study was conducted that measured the total brain volume {TBVJ [in mmal of patients that had schizophrenia and patients that are considered normal. Table #1 contains the TBV of the normal patients and Table #2 contains the TEN of schizophrenia patients ("SOCR data Oct2009,\" 2013]. 3} Table #1: Total Brain Volume (in mm of Normal Patients 166340? 1533940 12994911535137 143139! 1593693 1453510 1650343 1233921 1366346 1326402 1503005 1424990 1317156 1441045 1463493 165020 1523045 1441636 1432033 1420416 1430121 136031! 1410213 1524303 1502202 120334 1319937 163399! 1292641 15 125?1 1635913 Table #2: Total Brain Volume [in mm3} of Schizophrenia Patients 1331??? 148?886 10660?5 129?32? 1499983 1861991 13683?8 14?6891 1443??5 133?82? 165825 1588132 1698-182 1569413 11??002 138?893 1483?63 168895! 1563593 131?885 1420249 1363859 12389?9 1286638 1325525 15885?3 14?625 1648209 135405 1354649 Let #1 = mean TB? of patients that are considered normal. Let #2 = mean TBV of patients that had schizophrenia. Compute a 90% confidence interval for the difference in TBV of normal patients and patients with Schizophrenia. (i) For the sample from population with mean = /, : Determine sample mean x, and sample standard deviation s, Enter sample mean to nearest integer, then comma, then sample standard deviation to nearest integer. Examples of correctly entered answers: 1332,112 -15478,3651 A/ (ii) For the sample from the population with mean = /2 : Determine sample mean xz and sample standard deviation $2Enter sample mean to nearest integer, then comma, then sample standard deviation to nearest integer. Examples of correctly entered answers: 1332,112 -15478,3651 A/ (iii) Enter the level of significance aused for this interval estimate: Enter in decimal form.
