Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x= 101.08, y=101.2 r= 0.840, P-value = 0.000, and y= 3.71 + 0.96x, where x represents the 1Q score of the husband. Find the best predicted value of y giw that the husband has an IQ of 102? 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 O (Round to two decimal places as needed.)

Question
Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x = 101.08, y= 101.25,
r= 0.840, P-value = 0.000, and y = 3.71 + 0.96x, where x represents the IQ score of the husband. Find the best predicted value of y given
that the husband has an IQ of 102? 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 ŷ is O.
