Question

Suppose IQ scores were obtained for 20 randomly seleceted sets of twins. The 20 pairs of measurements yeild x=101.75, y=102.3, r= 0.909, p value= 0.000, and Y (with the ^ above it) = 18.79 + 1.19x, where x represents the IQ score of the twin born first. Find the best predicted value of Y(^) given that the twin born first has and IQ of 95? use a significance level of 0.05.

The best predicted value of Y(^) is ... ?
