The regression line $$\hat { Y }$$
= 3 + 2X has been fitted to the data points (4,14), (2,7),and (1,4).The sum of the residuals squared will be 8.0.

Question

= 3 + 2X has been fitted to the data points (4,14), (2,7),and (1,4).The sum of the residuals squared will be 8.0.

Quizplus · Accepted Answer

The sum of the squared residuals is calculated by finding the difference between the actual and predicted values for each data point, squaring those differences, and summing them. For the given data points, this sum is not 8.0.
