You land a job at an online marketing/consulting firm after attaining a business degree with an emphasis in statistics. You walk into your office on the first day and there is an assignment sitting upon your desk. The firm was recently hired by ImpulseBuy Now.com (a famous online clearing house for as-seen-on-TV junk items).
