Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x = 98.9, y= 100.6, r=0.869, P-value = 0.000, and y = 17.71 + 0.84x, where x represents the IQ score of the wife. Find the best predicted value of y given that the wife has an IQ of 93? 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. Critical Values of the Pearson Correlation Coefficient r (Round to two decimal places as needed.) a = 0.05 0.950 0.878 NOTE: To test Ho: p=0 against H,: p#0, reject H, if the absolute value of r is greater than the critical value in the table. a = 0.01 4 0.990 0.959 6 0.811 0.917 7 0.754 0.875 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 0.444 0.575 Enter your answer in the answer box. 20 0.561 25 0.396 0.505
