Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x= 100.88, y= 100.7, r=0.914, P-value = 0.000, and y = - 10.01+1.1x, where x represents the IQ score of the wife. Find the best
predicted value of y given that the wife has an lIQ of 90? Use a significance level of 0.05.
