Suppose IQ scores were obtained from randomly chosen siblings. For 20 such pairs of people, the linear correlation coeffiecient is 0.896 and the equation of the regression line is y=-6.54 + 1.06x where x represents the IQ score of the older child. Also, the 20x values have a mean of 103.02 and the 20y values have a mean of 102.9. What is the best predicted IQ of the younger child, given that the older child has an IQ of 91? Use a significance level of 0.05.
The best predicted IQ of the younger child is_______
