Instruction 11-4
a Hotel Chain Has Identically Sized Resorts in Five

question 128

Short Answer

Instruction 11-4
A hotel chain has identically sized resorts in five locations. The following data resulted from analysing the hotel guests on randomly selected days in the five locations.
$$\begin{array} { | l | l | l | l | l | l | } \hline \text { ROW } & \text { Caymen } & \text { Pennkapmp } & \text { California } & \text { Mayaguez } & \text { Maui } \\\hline 1 & 28 & 40 & 21 & 37 & 22 \\\hline 2 & 33 & 35 & 21 & 47 & 19 \\\hline 3 & 41 & 33 & 27 & 45 & 25 \\\hline\end{array}$$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$$\text { Analysis of Variance }$
$\begin{array} { | l | l | l | l | l | l | } \hline{ \text { Analysis of Variancs } } \\\hline \text { Source } &\text { d f }& \text {SS} & \text { MS } & \text { F }& \text { p }\\\hline \text { Location } & 4 & \mathbf { 9 6 3 . 6 } & & 11.47 & 0.001 \\\hline \text { Error } & 10 & \mathbf { 2 1 0 . 0 } & & & \\\hline \text { Total } & & & & & \\\hline\end{array}$
-Referring to Instruction 11-4,the null hypothesis for Levene's test for homogeneity of variances is
A. $H _ { 0 } : { } ^ { \sigma _ { A } ^ { 2 } } = { } ^ { \sigma _ { B } ^ { 2 } } = { } ^ { \sigma _ { C } ^ { 2 } } = { } ^ { \sigma _ { D } ^ { 2 } }$
B. $H _ { 0 } : M _ { A } = M _ { B } = M _ { C } = M _ { D }$ .
C. $H _ { 0 } : \pi _ { A } = \pi _ { B } = \pi _ { C } = \pi _ { D }$ .
D. $H _ { 0 } : \mu _ { A } = \mu _ { B } = \mu _ { C } = \mu _ { D }$ .
