Multiple Choice

TABLE 11-2
An airline wants to select a computer software package for its reservation system. Four software packages (1, 2, 3, and 4) are commercially available. The airline will choose the package that bumps as few passengers, on the average, 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 obtained, which gives rise to the following Excel output:
$$\begin{array}{l}\text { ANOVA }\\\begin{array} { l c c c c c c } \hline \text { Source of Variation } & \text { SS } & \text { df } & \text { MS } & F & p \text {-value } & \text { F crit } \\\hline \text { Between Groups } & 212.4 & 3 & & 8.304985 & 0.001474 & 3.238867 \\\text { Within Groups } & 136.4 & & 8.525 & & & \\\\\text { Total } & 348.8 & & & & & \\\hline\end{array}\end{array}$$
-Referring to Table 11-2, the among-group (between-group) mean squares is

• A) 70.8.
• B) 212.4.
• C) 8.525.
• D) 637.2.
