Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x = 99.81, y = 100.1, r= 0.876, P-value = 0.000, and y = 26.12 + 0.74x, where x represents the IQ score of the wife. Find the best predicted value of y given that the wife 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 predicted value of y is. (Round to two decimal places as needed.)
