Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x = 102.36, y = 104.7, r=0.949, P-value = 0.000, and y = 0.27 + 1.02x, where x represents the IQ score of the twin born first. Find the best predicted value of y given that the twin born first has an IQ of 99? 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. (Round to two decimal places as needed.) ...

**Transcription for Educational Website** Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield \(\bar{x} = 102.36\), \(\bar{y} = 104.7\), \(r = 0.949\), P-value = 0.000, and \(\hat{y} = 0.27 + 1.02x\), where \(x\) represents the IQ score of the twin born first. Find the best predicted value of \(\hat{y}\) given that the twin born first has an IQ of 99. Use a significance level of 0.05. [
