Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x= 105.52, y = 106.85, r=0.896, P-value = 0.000, and y = - 1.65 + 1.03x, where x represents the IQ score of the younger child. Find the best predicted value of y given that the younger child has an 1Q of 103? Use a significance level of 0.05. Click the icon to view the critical values of the Pearson correlation coefficient r. The best predicted value of y is. (Round to two decimal places as needed.)
