To Jigsmap please answer my question

Suppose IQ scores were obtained from randomly selected siblings. For 20 such pairs of people, the linear corre coefficient is 0.842 and the equation of the regression line is ^y =11.61+0.88x,where X represents the IQ score of the younger child. Also, the 20 x values have a mean of 99.6. What is the best predicted IQ of the older child, given that the younger child has an IQ of 106? Use a significance level of 0.05. Click the icon to view the critical values of the Pearson correlation coefficient r.

The best predicted IQ of the older child is--------(round to three decimal places.

Thank you so much.

Explanation / Answer

e best predicted IQ of the older child is from linear regression equation from abvoe:

y=11.61+0.88*106=104.890
