Suppose IQ scores were obtained from randomly selected siblings. For 20 such pairs of people, the linear correlation coefficient is 0.913 and the equation of the regression line is ybar = -15.61 + 1.16x, where x represents the IQ score of the older child. Also, the 20 x values have a mean of 97.05 and the 20 y values have a mean of 97.4. What is the best predicted IQ of the younger child, given that the older child has an IQ of 98? Use a significance level of 0.05.
The best predicted IQ of the younger child is __.
