Suppose IQ scores were obtained for 20 randomly selected sets of twins, The 20 pairs of measurements yield x 101.14, y= 99.35, r=0.951, P-value0.000, and y -9+ 1.07x, where x represents the IQ score of the twin bom first. Find the best predicted value of y given that the twin born first has an IQ of 917 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.)
