Suppose IQ scores were obtained from randomly selected couples. For 20 such pairs of people, the linear correlation coefficient is 0.896 and the equation of the regression line is y^=6.22 + 0.95x, where x represents the IQ score of the wife. Also, the 20 x values have a mean of 98.48 and the 20 y values have a mean of 100.05. What is the best predicted IQ of the husband, given that the wife has an IQ of 107? Use a significance level of 0.05.
