Determining best predicted iq of the older child

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.

The best predicted IQ of the older child is___
