Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x overbarequals95.16, y overbarequals94.9, requals0.916, P-valueequals0.000, and ModifyingAbove y with caret equals negative 22.96 plus 1.24 x, where x represents the IQ score of the younger child. Find the best predicted value of ModifyingAbove y with caret given that the younger child has an IQ of 100? Use a significance level of 0.05.
