MAT 131 ONLN2 (Fall 2UTM Homework: Chapter 10 Save Score: 0 of 1 pt 14 of 23 (14 complete) Score: 35 X) 10.3.5 Question Help Suppose IQ scores were obtained from randomly selected twins. For 20 such pairs of people, the linear correlation coefficient is 0.927 and the equation of the regression line is y =-6.5 + 1.1x, where x represents the IQ score of the twin born second. Also, the 20 x values have a mean of 100.56 and the 20 y values have a mean of 104.05. What is the best predicted IQ of the twin born first, given that the twin born second has an IQ of 95? Use a significance level of 0.05 Click the icon to view the critical values of the Pearson correlation coefficient The best predicted IQ of the twin born first is (Round to two decimal places as needed. nc Enter your answer in the answer box and then click Check Answer All parts showing Check Answer Clear All 69Explanation / Answer
The given model is
y hat= -6.5+1.1(x)
where x is IQ of the twin born
Now when x=95
y hat= -6.5+1.1*(65)=65
