Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x = 98.09, y = 98.2, r = 0.872, P-value = 0.000, and y = 6.5 + 0.93x, where x represents the IQ score of the wife. Find the best predicted value of y given that the wife has an IQ of 91? 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.)Critical Values of the Pearson Correlation Coefficient r n a = 0.05 a = 0.01 NOTE: To test Ho: p = 0 0.950 0.990 against H1: p #0, reject Ho 0.878 0.959 if the absolute value of r is 6 0.811 0.917 greater than the critical 0.754 0.875 value in the table. 8 0.707 0.834 9 0.666 0.798 10 0.632 0.765 11 0.602 0.735 12 0.576 0.708 13 0.553 0.684 14 0.532 0.661 15 0.514 0.641 16 0.497 0.623 17 0.482 0.606 18 0.468 0.590 19 0.456 0.575 20 0.444 0.561 25 0.396 0.505 30 0.361 0.463 35 0.335 0.430 40 0.312 0.402
