A Human Factors Engineer developed predictions about automobile accidents at intersections based on the distance drivers had to turn their heads to check traffic. These predictions lead to the expectation that a 3:2:1 ratio would be found for 4-way intersections (?), Y-intersections (Y), and 3-way intersections (?). The following figures were obtained from intersections with equal traffic flow. Test the engineer's theory. $$\begin{array} { l l l }
( ? ) & ( \mathrm { Y } ) & ( \mathrm { T } ) \
116 & 60 & 24
\end{array}$$
