Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield X= 100.77. y = 103.5, r = 0.898, P-value - 0.000, and y = - 8.26 + 1.11x, where x represents the 10 score of the younger child. Find the best predicted value of y given that the younger child has an 1Q of 108? Use a significance level of 0.05 Question: The best predicted value of y is?
