Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x = 103.51, y = 102.4, r=0.972, P-value = 0.000, and ŷ= -4.6+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 IQ of 95? 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 ofŷ is. (Round to two decimal places as needed.)
