Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x = 100.13, y = 101.3, r=0.890, P-value = 0.000, and y = 3.27 +0.98x, where x represents the IQ score of the twin born first. Find the best predicted value of y given that the twin born first 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 of y is (Round to two decimal places as needed.)
