Question

A scatter plot containing the point (5, 29) has the regression equation yˆ=5x+2 .

What is the residual e when x = 5?



Enter your answer in the box.

e =

Answer 1

ε₀= 0.035

Explanation:

The question is on residual/ error which is the vertical distance between the actual value of y and the estimated value of y.

General formulae is;

ε₀= y₀ - y₁

From the graph attached, the point on the line y=5x+2 is (5.407,29.035)

ε₀= 29.035- 29.000

ε₀= 0.035
