Question
Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x=102.11, y=103.9, r=0.932, P-value=0.000, and y=7.93+1.1x, where
Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x=102.11, y=103.9, r=0.932, P-value=0.000, and y=7.93+1.1x, where x represents the IQ score of the younger child. Find the best predicted value of y given that the younger child has an IQ of 91? Use a significance level of 0.05
