Intro to Stats: Videos & Practice Problems

According to the least-squares principle, the regression line is the one that makes the sum of squared residuals as small as possible. Using the dinner duration (x) and tip (y) data shown below, along with the regression equation find the sum of the squares of the residuals.
$ŷ=1.10+0.102x$
Recall that the residual for each observation is:$e_{i}=y_{i}-ŷ_{i}$
