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.

B: 2.5, 2.1, 1.9, 1.6 $\quad$ D: 0.8, 1.3, 1.1, 0.7
Interpret the results of the analysis summarized in the following table:
$\begin{array}{llllll}\text { Source } & \text { df } & \text { SS } & \text { MS } & \text { F } & \text { PR }>\text { F } \\\hline \text { Neighborhoods } & & 3.1819 & & & \\& 1.0606 & 10.76 & 0.001 & & \\\text { Error } & 12 & & & &\\\text { Total }&& 4,3644 \end{array}$
