Suppose IQ scores were obtained for 20 selected sets of twins. The 20 pairs of measurements yield x= 103.22, y=105.7, r=0.947, P-value=0.000, and y=-12.53 1.15x, where x represents the IQ score of the twin bom first. Find the best predicted value of y given that the twin bom first has an IQ of 927 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 is (Round to two decimal places as needed.)
