Answer

Explanation:

Step1: Recall residual formula

Residual = Given - Predicted

Step2: Calculate value of a

a = 6.1 - 5.2 = 0.9

Step3: Calculate value of b

b = 7.4 - 8.4=-1

Step4: Calculate value of c

c = 11 - 11.6=-0.6

Step5: Calculate value of d

d = 15 - 14.8 = 0.2

Answer:

a = 0.9 b = -1 c = -0.6 d = 0.2
