ome researchers believe that education influences IQ. One researcher specifically believes that the more education a person has, the higher, on average, will be his or her IQ. The researcher sets out to investigate this belief by obtaining eight pairs of identical twins reared apart. He identifies the better-educated twin as Twin A and the other twin as Twin B for each pair. The data for the study are given in the table below. Does the data give good statistical evidence, at the 0.05 level of significance, that the twin with more education is likely to have the higher IQ? Use the Wilcoxon Signed Ranks Non-Parametric test and a separate Parametric test to provide good statistical evidence to support your answer. Pair 1 2 3 4 5 6 7 8 Twin A 103 110 90 97 92 107 115 102 Twin B 97 103 91 9
