Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x=102.22​, y=102​, r=0.897​, ​P-value=​0.000, and y=2.09+0.98x​, 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 105​? Use a significance level of 0.05.   LOADING...
