Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x = 102.83, y=100.85, r=0.881, P-value=0.000, and y=-24.66 +1.22x, where x represents the IQ score of the younger child. Find the best predicted value of y given that the younger child has an IQ of 96? 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 ŷ is. (Round to two decimal places as needed.)
