Suppose IQ scores were obtained from randomly selected twins. For 20 such pairs of people, the linear corelation coefficient is 0.897 and the equation of the regression line is y(^)=7.54 + 1.07x, where x represents the IQ score of the younger child. Also, the 20 x values have mean of 101.11 and the 20 y values have mean of 100.9. What is the best predicted IQ of the older child, given that the twin born second has an IQ of 97? Use a significance level of .05.
