Question

A clinical psychology student wanted to determine if there is a significant difference in the Picture Arrangement scores (a subtest of the WAIS-IV that some feel might tap right-brain processing powers) between groups of right- and left-handed college students. The scores were as follows:

Picture Arrangement Scores
Left-Handed Students	Right-Handed Students
12	8
10	10
12	10
14	12
12	11
10	6
8	7
13	9
7	11

Is there a significant difference in the Picture Arrangement scores between the right- and left-handed students? Use α = .05 in making your decision. Be sure to state your hypotheses and include the following, if necessary – test statistic, degrees of freedom, computations, critical value(s)…
