Answer:
Residual in this case is -4.215
Step-by-step explanation:
A residual can be defined by
Residual = Actual value - Predicted value
We are given:
Predicted value of y = 34.215
Actual value of y = 30
Putting values in the formula:
Residual = Actual value - Predicted value
Residual = 30 - 34.215
Residual = -4.215
So, residual in this case is -4.215
