We measure the self-esteem scores of a sample of statistics students, reasoning that this course may lower their serf-esteem relative to that ofthe typical college student (u = 55 and ox = 11.35). we obtain these scores: 44 55 39 17 27 38 36 24 36(a) summarize your sample data. (b) is this a one-tailed or two-tailed test? why? (c) what are i10 and fe? (d) computezobt (e) with a = .05, what is zcrit? (f) what should we conclude about the relationship here? (chs. 2, 3, 4, 10)

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
