Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x = 100.29, y = 101.75, r = 0.830, P-value = 0.000, and y = 6.74 + 0.95x, 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 103? 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.)
