Also, the 20 x values have a mean of 97.59 and the 20 y values have a mean of 97.5. what is the best predicted IQ of the younger child, given that the older child has an IQ of 95? Use a significance level of .05.
The best predicted IQ of the younger child is ?
Explanation / Answer
from above given linear equation ; the best predicted IQ of the younger child is =10.42+0.89*95=94.97
