In a psychology experiment, 140 students were divided into majors emphasizing left-hemisphere brain skills (e.g., philosophy, physics, and mathematics) and majors emphasizing right-hemisphere skills (e.g., art, music, theater, and dance). They were also classified into one of three groups on the basis of hand posture (right non-inverted, left inverted, and left non-inverted). The data are as follows:

Do these data show sufficient evidence to reject the claim that the choice of college major is independent of hand posture? Let α = 0.025.
