Linear Regression & Least Squares Method: Videos & Practice Problems

According to the least-squares principle, the regression line is defined as the unique linear model that minimizes the sum of squared residuals. Using the dinner duration data provided below and the regression equation, identify the residuals for all $10$ observations by comparing the actual tip amount ($y$) to the predicted tip amount ($\hat{y}$).
$\hat{y}=1.10+0.102x$
