Package is used to make reservations for 5 randomly selected weeks and data on the number of
Passengers that are bumped over a month are collected.(A total of 20 weeks was included in the
Experiment.) The variability of the number of passengers that are bumped is found to be roughly
The same for the 4 packages.The distribution on the number of passengers that are bumped has
Been found out to be right-skewed for package 1 and 4, left-skewed for package 2 and normal for
Package 3.Which of the following tests will be the most appropriate to find out if the mean
Number of passengers being bumped over a month is the same across the 4 packages?
