About 37% of the variation in arm span is accounted for by the linear relationship formed with the foot length. About 65% of the variation in foot length is accounted for by the linear relationship formed with the arm span. O About 63% of the variation in arm span is accounted for by the linear relationship formed with the foot length. O About 63% of the variation in foot length is accounted for by the linear relationship formed with the arm span.
