The file P17_19.xlsx contains various data on 325 metropolitan cities in the United States. Cell comments in row 1 explain some of the variables. A Microsoft Data Mining add-in (not discussed here) was used to cluster these cities, with the results shown in the file. There are four clusters, cluster membership is listed in column V of the Data sheet, and the composition of clusters is in the Categories Report sheet. Study this report carefully, and then write a short report about the clusters. Does the clustering make sense? Can you provide descriptive, meaningful names for the clusters?
