An airline wants to select a computer software package for the reservation system. Four software packages (1,2,3,4) are commercially available. The airline will choose the package that bumps as few passengers, on average, as possible during a month.

Question
An airline wants to select a computer software package for the
reservation system. Four software packages (1,2,3,4) are
commercially available. The airline will choose the package that

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 output analysis as
in Output 1. Based on Output 1, at a significance level of 1%,
