Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield y = 97.75, r 0.924, P-value = 0.000, and y = 0.11 + 0.99x, where x represents the IQ score of the older child. Find the best predicted value of y given that the older child has an IQ of 95? Use a significance level of 0.05. %3D 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.)
