Please show work in excel.

1.  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?
