Suppose iq scores were obtained from randomly selected couples. for 20 such pairs of people, the linear correlation coefficient is 0.899 and the equation of the regression line is modifyingabove y with caret equals 0.98 plus 0.97 x, where x represents the iq score of the husband. also, the 20 x values have a mean of 98.03 and the 20 y values have a mean of 96.05. what is the best predicted iq of the wife, given that the husband has an iq of 104? use a significance level of 0.05.
