for 20 such pairs of people the linear correlation coefficient is 0.926 and the equation of the regression line is y=-22.61+1.23x, where x represents the IQ score of the husband. Also, the 20 x values have a mean of 97.71 and the 20y values have a mean of 97.2. What is the best predicted IQ of the wife, given the husband has an IQ of 103? where do I even start?
