Multiple Choice

Instruction 11-1
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 as possible during a month. An experiment is set up in which each package is used to make reservations for five 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 Microsoft Excel output:
$$\begin{array}{l}\text { ANOVA }\\\begin{array} { | l | c | c | c | c | c | c | } \hline \begin{array} { l } \text { Source of } \\\text { Varlation }\end{array} & \boldsymbol { S S } & d f & \boldsymbol { N S } & \boldsymbol { F } & \rho _ { \text {-vahe } } & \text { F crit } \\\hline \text { Between Groups } & \mathbf { 2 1 2 . 4 } & \mathbf { 3 } & & \mathbf { 8 . 3 0 4 9 8 5 } & \mathbf { 0 . 0 0 1 4 7 4 } & \mathbf { 3 . 2 3 8 8 6 7 } \\\hline \text { Within Groups } & \mathbf { 1 3 6 . 4 } & & \mathbf { 8 . 5 2 5 } & & & \\\hline & & & & & & \\\hline \text { Total } & \mathbf { 3 4 8 . 8 } & & & & & \\\hline\end{array}\end{array}$$
-Referring to Instruction 11-1,at a significance level of 1%,

• A) there is insufficient evidence to conclude that the average numbers of customers bumped by the 4 packages are not all the same.
• B) there is sufficient evidence to conclude that the average numbers of customers bumped by the 4 packages are all the same.
• C) there is insufficient evidence to conclude that the average numbers of customers bumped by the 4 packages are all the same.
• D) there is sufficient evidence to conclude that the average numbers of customers bumped by the 4 packages are not all the same.
