Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x = 101.7, y = 101.2, r=0.869, P-value = 0.000, and y= -1.24 + 1.01x, 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 109? 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.)
