A scatter diagram includes the following data points: $$\begin{array} { | c | c | c | c | c | c | }
\hline x & 3 & 2 & 5 & 4 & 5 \
\hline y & 9 & 6 & 11 & 11 & 15 \
\hline
\end{array}$$ Two regression models are proposed:
Model 1: y-hat = 1.85 + 2.40x.
Model 2: y-hat = 1.79 + 2.54x.
Using the least squares method, which of these regression models provides the better fit to the data? Why?
