Four sets of identical twins were selected at random from a computer database of identical twins. One child was selected at random from each pair to form an “experimental group” who were sent to school. The other four children were kept at home as a control group. At the end of the year IQ scores were obtained. Does this evidence justify the conclusion that lack of school has a depressing effect on IQ scores? Test with the p-value approach. pair  Experimental group Control A 110 111 B 125 120 C 139 128 D 142 135
