Four software packages (1, 2, 3, and 4) are commercially available. The airline will choose the package that bumps as few passengers as possible during a month. An exp is set up in which each package is used to make reservations for 5 randomly selected weeks. (A total of 20 weeks was included experiment.) The number of passengers bumped each week is obtained, which gives rise to the following Excel output: AN OVA Source qf Variation SS df MS F pvalue P crit Between Groups 212.4 3 8.304985 0.001474 3.238867 Within Groups 136.4 8.525 Total 348.8 4) Referring to Table 111, the among-group (between group) mean squares is A) 8.525.
