Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x = 100.12, y = 100.8, r=0.869, P-value = 0.000, and y = 3.57 +0.97x, where x represents he IQ score of the husband. Find the best predicted value of y given that the husband has an IQ of 94? Use a significance level of 0.05. Click the icon to view the critical values of the Pearson correlation coefficient r. The best...
