question 121

Multiple Choice

TABLE 11-2
A realtor wants to compare the mean sales-to-appraisal ratios of residential properties sold in four neighborhoods (A, B, C, and D) . Four properties are randomly selected from each neighborhood and the ratios recorded for each, as shown below.
A: 1.2, 1.1, 0.9, 0.4 C: 1.0, 1.5, 1.1, 1.3
B: 2.5, 2.1, 1.9, 1.6 D: 0.8, 1.3, 1.1, 0.7
Interpret the results of the analysis summarized in the following table:
$\begin{array}{llllll}\hline \text { Source } & d f & \text { SS } & \text { MS } & F & \mathrm{PR}>\mathrm{F} \\\hline \begin{array}{l}\text { Neighborhoods } \\\end{array} & & 3.1819 & 1.0606 & 10.76 & 0.001 \\\text { Error }&12\\\hline\text { Total } & & 4.3644 & & & \\\hline\end{array}$
-Referring to Table 11-2, the null hypothesis for Levene's test for homogeneity of variances is

• A) H?: ?A = ?B = ?C = ?D.
• B) H?: MA = MB = MC = MD.
• C) \(H _ { 0 } : \sigma _ { A } ^ { 2 } = \sigma _ { B } ^ { 2 } = \sigma _ { C } ^ { 2 } = \sigma _ { D } ^ { 2 }\)
• D) H?: ?A = ?B = ?C = ?D.
