A.    The Pair O' Dice Casino [which employs six hundred forty full-time workers] in Hawaiian Gardens, California, refuses to hire female bouncers on the grounds that they are insufficiently strong and intimidating enough to effectively perform the job.  During the trial in U.S. District Court for sex discrimination brought by a group of women denied jobs as bouncers at the casino (the EEOC had issued a Right to Sue letter after concluding that there was insufficient evidence supporting the charge), the general manager, Clayton Tyson, defended the policy.  Tyson testified that "everyone in the world can tell, simply by looking, that the physical capability of women is less imposing than that of men." 

What additional evidence, if any, could the casino offer to bolster its defense?
