Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x=99.05, y = 100.15, r=0.837, P-value = 0.000, and y=19.19+0.82x, where x represents the IQ score of the wife. Find the best predicted value of y given that the wife has an IQ of 108? 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 ŷ is. (Round to two decimal places as needed.)
