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
