Suppose 10 scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yieldx-101.82.98.75, 0.920, P-value=0.000, and y=-2.64+1x. 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 1077 Use a significance level of 0.05.
