Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x= 98.14, y = 98.05, r=0.819, P-value = 0.000, and y = 16.2 + 0.83x, where x represents the IQ score of the wife. Find the best predicted value of y given that the wife has an IQ of 97? Use a significance level of 0.05. E Click the icon to view the critical values of the Pearson correlation coefficient r. The best predicted value of y isn. (Round to two decimal places as needed.)
