In a study conducted to investigate browsing activity by shoppers, each shopper was initially classified as a nonbrowser, light browser, or heavy browser. For each shopper, the study obtained a measure to determine how comfortable the shopper was in a store. Higher scores indicated greater comfort. Suppose the following data were collected.
| Non Browser | Light Browser | Heavy Browser | 
| 8 | 9 | 10 | 
| 9 | 10 | 12 | 
| 10 | 9 | 10 | 
| 7 | 8 | 12 | 
| 7 | 11 | 9 | 
| 8 | 8 | 11 | 
| 9 | 10 | 10 | 
| 8 | 9 | 12 | 
A. use .05 to test for a difference among mean comfort scores for the three types of browsers .
