Multiple Choice

TABLE 11-3
A realtor wants to compare the average 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: $\quad 1.2,1.1,0.9,0.4 \quad$ C: $\quad 1.0,1.5,1.1,1.3$
B: $\quad 2.5,2.1,1.9,1.6 \quad$ D: $\quad 0.8,1.3,1.1,0.7$

Interpret the results of the analysis summarized in the following table:
$\begin{array}{llllll}\text { Source } & \text { df } & \text { SS } & \text { MS } & \text { F } & \text { PR }>\text { F } \\\text { Neighborhoods } & & 3.1819& 1.0606 & 10.76 & 0.001 & & \\\text { Error } & 12 & & & & \\\text { Total } & & 4.3644 & &\end{array}$
