Suppose IQ scores were obtained from randomly selected couples. For 20 such pairs of people, the linear correlation coefficient is 0.932 and the equation of the regression line is y=?16.91+1.2x, where x represents the IQ score of the wife. Also, the 20 x values have a mean of 100.87 and the 20 y values have a mean of 103.95. What is the best predicted IQ of the husband, given that the wife has an IQ of 90? Use a significance level of 0.05.
