Suppose IQ score were obtained from a randomly selected siblings.For such 20 pairs of people the linear corelation is 0.907 and the equation of regression line is y= 3.92+0.95x ,where x represents the iq score of the younger child. Also ,the 20 x values have a mean if 99.85 and the 20 y values have a mean of 99.25.What is the best predicted IQ of the older child,given that the younger child has an IQ of 104?Use a significance level of 0.05.
