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 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. Package 1: 12, 14, 9, 11, 16b. Package 2: 2, 4, 7, 3, 1c. Package 3: 10, 9, 6, 10, 12d. Package 4: 7, 6, 6, 15, 12The alternative hypothesis is:

A. The four package means are not different in the sample

B. The four package means are different in the sample

C. The four package means are not different in the population

D. The four package means are different in the population
