Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x= 103.69, y = 104.5, r=0.862, P-value=0.000, and ŷ = 14.27 +0.87X, where x represents the IQ score of the twin born second. Find the best predicted value of ý given that the twin born second has an IQ of 90? Use a significance level of 0.05.
