Transcribed Image Text:The group of 25 victims scored an average of 25.3 with a sample standard deviation of 9 on the depression
scale. The group of 23 bully-victims scored an average of 20.5 with a sample standard deviation of 8 on the
same scale. You do not have any presupposed assumptions about whether victims or bully-victims will be
more depressed, so you formulate the null and alternative hypotheses as:
H. Hvictims - Hbully-victims = 0
H1: Hvictims Hbully-victims 70
You conduct an independent-measures t test. Given your null and alternative hypotheses, this is a
a) Two-tailed
b) one-tailed
The degree of freedom is a) 46 b) 48 c) 24 d) 22
and for an alpha of .01, the critical t is +/- a) 2.704
