husband has an IQ of 105? Use a significance level of 0.05 Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x = 97.02, y = 96.85, r=0.902, P-value =0.000, and y = 2.5 +0.97x, where x represents the IQ score of the husband. Find the best predicted value of y given that the 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 - X (Round to two decimal places as needed.) Critical Values of the Pearson Correlation Coefficient r x = 0.05 X =0.01 NOTE: To test Ho: p= 0 .950 ).990 0.878 against H,: p #0, reject Ho 0.959 0.811 0.917 if the absolute value of r is 0.754 greater than the critical 0.875 value in the table.
