Package 1: 12,14,9,11,and 16 Package 2: 2,4,7,3,and 1
Package 3: 10,9,6,10,and 12 Package 4: 7,6,6,15,and 12
Which of the following tests is appropriate for testing the software's use?

The appropriate test for comparing the mean number of passengers bumped by each software package is the one-way ANOVA F test. This test allows us to determine if there is a significant difference between the means of multiple groups. The experiment involves four groups (software packages), and we need to determine which one has the lowest mean number of passengers bumped. Therefore, the one-way ANOVA F test is the best choice for this scenario.
