Consider the following pairs of observations: $$\begin{array} { | c | c | c | c | c | c | }
\hline x & 2 & 3 & 5 & 5 & 6 \
\hline y & 1.3 & 1.6 & 2.1 & 2.2 & 2.7 \
\hline
\end{array}$$ a. Construct a scattergram for the data. Does the scattergram suggest that y is positively linearly related to x? b. Find the slope of the least squares line for the data and test whether the data provide sufficient evidence that y is positively linearly related to x. Use α = .05.
