Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x = 99.37, y=98.55, r=0.859, P-value = 0.000, andy = 10.94 +0.88x, where x represents the IQ score of the older child. Find the best predicted value of y given that the older child has an IQ of 105? Use a significancelevel of 0.05.10CritPearson.pdfO A. 98.55OB. 99.37O C. 103.34O D. 0.88
