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 B: 2.5, 2.1, 1.9, 1.6 C: 1.0, 1.5, 1.1, 1.3 D: 0.8, 1.3, 1.1, 0.7 Interpret the results of the analysis summarized in the following table: Source df SS MS F PR >F Neighborhoods Error 3.1819 1.0606 10.76 0.001 12 Total 4.3644 Referring to Table 10-17, what should be the decision for the Levene's test for homogeneity of variances at a 5% level of significance? Seleccione una: O A. Reject the null hypothesis because the p-value is smaller than the level of significance. OB. Reject the null hypothesis because the p-value is larger than the level of significance. Oc. Do not reject the null hypothesis because the p-value is larger than the level of significance. OD. Do not reject the null hypothesis because the p-value is smaller than the level of significance.
