IQ scores were obtained randomly from selected twins at birth. For 20 such twins the linear correlation coefficient was 0.896 and equation of regression line is y= -3.02 + 1x, where x represents the iq score of the twin that was first born. Also the 20 x values has a mean of 103.2 and the 20 y values has a mean of 105.2. What is the best predicted IQ of the twin born second, given the first born twin has an IQ of 105?
