5. Is there a significant difference between the IQ scores of identical twins, where one member of the pair is reared by the natural parents and the other member is not? The following matched pairs data was obtained. Pair 1 2 3 4 5 6 7 8 9 10 Twin A 113 94 89 77 111 104 85 76 111 109 Twin B 109 100 86 80 117 107 85 84 125 108 Difference 4 -6 3 -3 -6 -3 0 -8 -14 1 Test to see if there is significant evidence that the true average difference in IQs of twins raised apart is something other than zero. Base your decision on a 0.05 level of significance. State hypotheses: Test Statistic P-value: Value: Decision: 5B. Create a 95% confidence interval for estimating the true average difference in IQ scores for twins raised apart. 5C. What does your interval suggest? Is it the same as what the test suggested? Can your interval be used to formally test? Why or why not
