An airline wants to select a computer software package for its
reservation system. Four software packages (1, 2, 3, and 4) are
commercially available. The airline will choose the package that bumps
as few passengers as possible during a month. An experiment is set up
in which each package is used to make reservations for 5 randomly
selected weeks. (A total of 20 weeks was included in the experiment.)
The number of passengers bumped each week is obtained, which gives
rise to the following Excel output for significance level of 1%:
