Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x=99.55,y=100.9, r=0.919, P-value=0.000, and y=11.54+0.9x, 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 94? Use a significance level of 0.05.
