Suppose 1Q scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x 101.53, y 101.85. 926, y-4.1+1.04x. where x ropresents the IQ score of the twin born first Find the best predicted value of y glven that the twin born fiest has an 1Q of 1017 Uso a significan level of 0 05. Click the icon to view the critical values of the Pearson corelation coetficient r. The best predicted valuo of y is (Round to two decimal places as needed)
