Solution:

In practice, the line of best fit or regression line is found when the sum of the squares of the residuals (∑(Y-h(X))²) is minimum.

The sum of the residuals (∑(Y – h(X))) is minimum

The sum of the absolute value of residuals (∑|Y-h(X)|) is maximum

The sum of the squares of the residuals (∑(Y-h(X))²) is minimum

The sum of the squares of the residuals (∑(Y-h(X))²) is maximum
