Question: Global IQ and shaken baby syndrome. As part of a larger study, Stipanicic, Nolin, Fortin, and Gobeil (2008) compared global IQ scores in a sample of 11 children (n1 = 11) with shaken baby syndrome (SBS) to those of 11 children without the syndrome (n2 = 11). Global IQ scores were 86.36 ± 15.16 (M ± SD) for children with SBS and 104.09 ± 12.10 (M ± SD) for children without SBS

(a) Test whether or not mean scores differed between groups, using a .05 level of significance. State the value of the test statistic and the decision to retain or reject the null hypothesis.
