Question 2

An airline wants to select a computer software package for its reservation system. Four software packages (1, 2, 3, and 4 ) are commercially available. An experiment is set up in which each 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?
 
  A) Kruskal-Wallis rank test
  B) One-way ANOVA F test for differences among more than two means
  C) Pooled-variance t test
  D) Paired t test
