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 the fewest mean number of 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 given below.How should the data be analyzed?
A)F test for differences in variances.
B)One-way ANOVA F test.
C)t test for the differences in means.
D)t test for the mean difference.

The experiment involves comparing the mean number of passengers bumped by each software package. Therefore, a one-way ANOVA F test should be used to determine if there are significant differences in the means of the four groups. The experiment is comparing the means of the number of passengers bumped for each software package. Therefore, a one-way ANOVA F test is the appropriate choice. The F test compares the variability between the groups (packages) to the variability within the groups. In this case, the goal is to minimize the mean number of passengers bumped, so the package with the lowest mean should be selected. By conducting the ANOVA, we can determine if there is a statistically significant difference in the means of the four packages.
