Question
Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements
yield x = 98.46, y = 99.4, r=0.883, P-value = 0.000, and y=-14.65 +1.16x, where x represents the IQ score of
the wife. Find the best predicted value of y given that the wife has an IQ of 101? 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.)
