  1. A recent Associated Press article out of Belgium indicated the European Union was considering a probe of computer makers after consumers complained that they were being overcharged for ink cartridges. Companies such as Canon, Hewlett Packard and Epson are the printer market leaders and make most of their printer related profits from sales of replacement ink cartridges.

    Suppose an independent test agency wishes to conduct a test to determine whether name-brand ink cartridges generate more color pages than competing generic ink cartridges. To test this theory 6 people are given both a name-brand color ink cartridge (Canon) and a generic color ink cartridge. The number of color pages each printed is counted. The agency used alpha =0.01.
