Critical Reasoning (CR) | Re: Nationwide, nearly two percent of all business

Nationwide, nearly two percent of all business school graduates will eventually be convicted of violations of the Securities and Exchange Act. Over the last five years, fully eight percent of all employees with MBAs at Schicksal, Barnham & Lampert, a top brokerage firm have been convicted of such violations. This dubious distinction clearly indicates that employees with MBAs at Schicksal, Barnham & Lampert are four times as corrupt as employees with MBAs at other brokeragefirms.

Which one of the following statements, if true, most weakens the argument above?
