Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x=98.05, y=97.95, r=0.741, P-value=0.000, and

y=43.31+0.56x, where x represents the IQ score of the husband. Find the best predicted value of

y given that the husband has an IQ of 98? Use a significance level of 0.05.
