9.11 The psychology departments of public universities in each of two different states accepted seven and nine applicants, respectively, for graduate study next fall. Their respective scores on the Graduate Record Examination are:

University X: 1200, 1220, 1300, 1170, 1080, 1110, 1130 University Y: 1210, 1180, 1000, 1010, 980, 1400, 1430, 1390, 970 The sample median and mean scores of applicants to the two universities are close to being equal, so an assumption of equal location may well be justified. Use the Siegel–Tukey test to see which university has the smaller variability in scores, if either.
