Studdy Solution
STEP 1
Assumptions1. The regression line for the predicted value of aptitude given age is Aptitude =111.5 -1.14 * Age. The age of the person for whom we want to predict the aptitude test score is17 years.
STEP 2
We need to substitute the given age into the regression equation to find the expected aptitude test score.
STEP 3
Substitute the age of17 years into the equation.
STEP 4
Calculate the result of the multiplication.
STEP 5
Subtract the result of the multiplication from111.5 to find the aptitude.
STEP 6
Round the result to the nearest whole number.
The expected aptitude test score for a person whose age is17 years is92.
