question 24

Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x = 101.25, y = 100.95, r = 0.883, P-value = 0.000, and y = 4.47 + 0.95x, where x represents the IQ score of the wife. Find the best predicted value of y given that the wife has an IQ of 90? 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.)
