Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x-101.85, y-99.3, r=0.880, P-value=0.000, and y=13.81 +0.84x, where x represents the IQ score of the twin born first. Find the best predicted value of y given that the twin born first has an IQ of 94? 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 ŷ is. (Round to two decimal places as needed.) KIED
