Data Set 11-6: Walking is valuable exercise. Does the size of the place you live have any relationship to how much walking you do? The following data (in miles per day) are entirely hypothetical, but represent a reasonable guess. (The place names for this problem are ordered from large to small and are from particular sources-can you identify a source or two?) $$\begin{array} { l c c c }
& \text { Gotham } & \text { Middletown } & \text { Grovers Corners } \
\Sigma \mathrm { X } & 16 & 24 & 32 \
\Sigma \mathrm { X } ^ { 2 } & 70 & 60 & 140 \
N & 4 & 12 & 8
\end{array}$$
-The proper critical value for Data Set 11-6 with alpha at the .05 level is
A) 3.47
B) 3.40
C) 5.78
