Suppose IQ scores were obtained from randomly selected couples. For 20 such pairs of people, the linear correlation coefficient is 0.897 and the equation of the regression line is y-bar= -2.05+1.04x, where x represents IQ score of the husband. Also, the 20 x values have a mean of 100.88 and the 20 y values have a mean of 102.7. What is the best predicted IQ of a randomly selected wife, given that her husband has an IQ of 94?
