Question

The regression line has been fitted to the data points (4, 8), (2, 5), and (1, 2). the sum of the squared residuals will be:_______

Answer 1

Based on the regression line, and the data points, the sum of squared residuals is 22.

What is the sum of squared residuals?

The squared residual can be found as:

= (y - 3 + 2x)²

For point (4 , 8)

= (8 - 3 - 2(4))²

= 9

For point (2 , 5)

= (5 - 3 - 2(2))²

= 4

For point (1, 2)

= (2 - 3 - 2(1))²

= 9

The sum of squared residuals is:

= 9 + 4 + 9

= 22
