Based on the graph, is there an association between handedness and type of transmission used?
In the US, the gear shift for a car with a manual
transmission is on the right-hand side of the driver. Does
this discourage those who are left-handed from driving a
manual transmission car? Several drivers were
surveyed about their handedness and the type of
transmission they have in their automobile. The results
are displayed below.
