Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x=97.43, y=96.8, r=0.862, P-value=0.000, and y = 0.13 +0.99x, where x represents the IQ score of the twin born second. Find the best predicted value of y given that the twin born second has an IQ of 110? 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.) ACCE
