Answer

Explanation:

Step1: Recall residual formula

Residual = Given value - Predicted value. So, Predicted value = Given value - Residual.

Step2: Calculate value of a

For age = 1, Given value = 15, Residual = 0.2. Then $a=15 - 0.2=14.8$.

Step3: Calculate value of b

For age = 2, Given value = 12, Predicted value = 11.9. Then $b=12 - 11.9 = 0.1$.

Step4: Calculate value of c

For age = 3, Given value = 9, Residual = 0. Then $c=9-0 = 9$.

Step5: Calculate value of d

For age = 4, Given value = 5, Predicted value = 6.1. Then $d=5 - 6.1=-1.1$.

Answer:

$a = 14.8$ $b = 0.1$ $c = 9$ $d=-1.1$
