Answer:
<em>Predicted height: 57.42 inches</em>
<em>Residual: 2.58 inches</em>
Step-by-step explanation:
<u>Regression Equation</u>
The regression equation for the height of the children (Hgt) and their age (Age) is given by the expression
Hgt = 24.3 + 2.76(Age)
We must compare the predicted value of the equation vs the real data point Age=12, Height=60
Computing the predicted height
Hgt = 24.3 + 2.76(12)
Hgt=57.42 inches
The residual is the difference between the real data point and the predicted value
R=60-57.42
R=2.58 inches
