Project #9250 - Chi-square test

Suppose Foot Locker strongly encourages its employees to   make formal suggestions to improve the store, the product, and   the working environment. Suppose a quality auditor keeps   records of the suggestions, the persons who submitted them,   and the geographic region from which they come. A possible   breakdown of the number of suggestions over a 3-year period   by employee sex and geographic location follows. Is there any   relationship between the sex of the employee and the geo-  graphic location in terms of number of suggestions? If they are   related, what does this relationship mean to the company? What   business implications might there be for such an analysis?
