Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x= 101.13, y = 103.5, r=0.867, P-value=0.000, and y = 6.25 +0.96x, where x represents the IQ score of the younger child. Find the best predicted value of y given that the younger child has an IQ of 101? 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.)

Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements
yield x = 101.13, y = 103.5, r=0.867, P-value = 0.000, and y = 6.25 +0.96x, where x represents the IQ score of
the younger child. Find the best predicted value of y given that the younger child has an IQ of 101? Use a
significance level of 0.05.
