Šuppose IQ scores were obtained from randomly selected siblings. For 20 such pairs of people, the linear correlation coefficient is 0.877 and the equation of the regression line is y = 20.45 +0.81x, where x represents the IQ score of the older child. Also, the 20 x values have a mean of 105.5 and the 20 y values have a mean of 105.75. What is the best predicted IQ of the younger child, given that the older child has an IQ of 103? Use a significance level of 0.05. E Click the icon to view the critical values of the Pearson correlation coefficient r. The best predicted IQ of the younger child is (Round to two decimal places as needed.)
