Segmentation Exercise:

This exercise builds directly off the Product Optimization Exercise we just did. The exercise

calls for follow up work to characterize the segments. For this exercise, apart from the files

from the Product Optimization Exercise, we need demographics data, which are provided in

this file: demographics$-$full.xlsx$.$ The demographics variable are: income $($in thousands of

dollars per year$),$ age $($in years$),$ sports $(=1$ if the person is sports active, $0$ if not$),$ gradschl

$(=1,$ if the person has a master's degree or beyond, $0$ if not$)$
