Suppose IQ scores were obtained from randomly selected twins. For 20 such pairs of people, the linear correlation coefficient is 0.897 and the equation of the regression line isy= 1.58 + 1x, where x represents the IQ score of the twin born first. Also, the 20 x values have a mean of 100.96 and the 20 y values have a mean of 99.86. What is the best predicted IQ of the twin born second, given that the twin born first has an IQ of 108? Use a significance level of 0.05.

The best predicted IQ of the twin born first is
