Suppose IQ scores were obtained for 20 randomly selected twins. The 20 pairs of measurements yielded x=100.37, y= 100.35, r= 0.874, P-value = 0.000 and ^y =-6.81 + 1.07x, where x represents the IQ score of the twin born second. Find the best predicted value of ^y given that the twin born second has an IQ of 101? use a significance level of 0.05
