Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x = 97.78, y = 96.9, r=0.830, P-value = 0.000, and y = 20.49+0.78x, 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 91? 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.)
