Suppose IQ scores were obtained from randomly selected siblings. For 20 such pairs of people, the linear correlation of coefficient is 0.880 and the equation of the regression linearis Y^=5.71 + 0.97x, where x represents the IQ score of the older child. Also, the 20 x values have a mean of 101.4 and the 20 y values have a mean of 103.65. What is the best predicted IQ of younger child, given that the older child has an IQ of 97? Use a significance leve of 0.05. THe best predicted IQ of the younger child is ____
