Question 785608: 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?

You can put this solution on YOUR website! 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?
-------
f(x)=-22.61+1.23x
f(103) = -22.61+1.23*103
f(103) = 104.08
