Suppose IQ scores were obtained from randomly selected siblings. For 20 such pairs of people, the linear correlation coefficient is 0.918 and the equation of the regression line is ŷ = - 7.03 + 1.08x, where x represents the IQ score of the younger child. Also, the 20 x values have a mean of 101.44 and the 20 y values have a mean of 102.15. What is the best predicted IQ of the older child, given that the younger child has an IQ of 108? Use a significance level of 0.05.
