Consider the following pairs of measurements: $\begin{array}{|c|c|c|c|c|c|}
\hline x & 5 & 8 & 3 & 4 & 9 \
\hline y & 6.2 & 3.4 & 7.5 & 8.1 & 3.2 \
\hline
\end{array}$

a. Construct a scattergram for the data.
b. Use the method of least squares to model the relationship between $x$ and $y$.
c. Calculate $S S E , s ^ { 2 }$, and s.
d. What percentage of the observed $y$-values fall within $2 s$ of the values of $\hat { y }$ predicted by the least squares model?
