SCENARIO 10-5
A hotel chain has identically small sized resorts in 5 locations in different small islands.The data that follow resulted from analyzing the hotel occupancies on randomly selected days in the 5 locations. $$\begin{array}{l}\begin{array} { l c c c c c } \text { ROW } & \text { Location A } & \text { Location B } & \text { Location C } & \text { Location D } & \text { Location E } \\\hline 1& 28 & 40 & 21 & 37 & 22 \\2 & 33 & 35 & 21 & 47 & 19 \\3 & 41 & 33 & 27 & 45 & 25\end{array}\\\text { Analysis of Variance }\\\begin{array} { l r r r c c } \hline \text { Source } & d f & \text { SS } & \text { MS } & F & p \\\hline \text { Location } & 4 & 963.6 & & 11.47 & 0.001 \\\text { Error } & 10 & 210.0 & & & \\\text { Total } & & & & & \\\hline\end{array}\end{array}$$
-Referring to SCENARIO 10-5, the null hypothesis for Levene's test for homogeneity of variances is

• A)\(H _ { 0 } : \mu _ { A } = \mu _ { B } = \mu _ { C } = \mu _ { D }\)
• B)\(H _ { 0 } : M _ { A } = M _ { B } = M _ { C } = M _ { D }\)
• C)\(H _ { 0 } : \sigma _ { A } ^ { 2 } = \sigma _ { B } ^ { 2 } = \sigma _ { C } ^ { 2 } = \sigma _ { D } ^ { 2 }\)
• D)\(H _ { 0 } : \pi _ { A } = \pi _ { B } = \pi _ { C } = \pi _ { D }\)
