Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x= 101.14, y = 102.6, r= 0.901, P-value = 0.000, and y = - 5.67 + 1.07x, where x represents the IQ score of the twin born se the best predicted value of y given that the twin born second has an IQ of 94? Use a significance level of 0.05. 9 Click the icon view the critical values of the Pearson correlation coefficient r. The best predicted value of y is. (Round to two decimal places as needed.)
