The best choice for analyzing the data is a one-way ANOVA F test since we are comparing the means of four groups (software packages) with each other to determine which one bumps as few passengers as possible. This test will also take into account the variability of the data within each group. F test for differences in variances is not relevant since we are not comparing the variances of the groups. T test for the mean difference and t test for the differences in means are not appropriate since we are comparing more than two groups.
