In a study conducted to investigate browsing activity by shoppers, each and every shopper was initially classified as a nonbrowser, light browser, or heavy browser. For each shopper, the study obtained a measure to find out how comfortable the shopper was in a store. Higher scores indicated greater comfort. Assume the following data were collected.
Light Heavy
Nonbrowser Browser Browser
6 3 8
7 4 10
8 3 8
5 2 10
5 5 7
6 2 9
7 4 8
6 3 10
