Question

A line of best fit predicts that when x equals 32

, y will equal 34.215 but y actually equals 30. what is the residual in this case

Answer 1

Residual in this case is -4.215

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
