The clustering analysis, geocoding, and symbology overlay should provide indications of any correlations between median income clustering and current operator usage. The software that is currently available through ArcGIS will be sufficient to carry out all analysis if the data is in the correct format prior to the tools being run. The software could additionally could provide hot spots of product use if the usage is coded into specific ranges which could provide information as to where to focus marketing.
This information is a good indication that I will not be able to only use median income as a predictor of potential sales sites. There needs to be some additional component that will refine the results. I think that clustering of median income could be a predictor of product use.
