Do these data show sufficient evidence to reject the claim that the choice of college major is independent of hand posture? let alpha =0.05
In a psychology experiment, 140 students were divided into majors em-
phasizing left-hemisphere (LH) brain skills (e.g. philosophy, physics, and
mathematics) and majors emphasizing right-hemisphere (RH) skills (e.g. art,
music, theater, and dance). They were also classified into one of three groups
on the basis of hand posture (right noninverted (RN), left inverted (LI), and
left noninverted (LN)). The data are as follows:
LH RH
RN 89 29
LI 5 4
LN 5 8
