Quizplus · Accepted Answer

The answer can be found in the first row of the "F test (ANOVA)" section, where the p-value is less than 0.05, indicating significant difference in means between the neighborhoods. Therefore, we can reject the null hypothesis and conclude that the sales-to-appraisal ratios are not equal across all four neighborhoods. The correct answer is A, which represents the number of neighborhoods with significantly different means compared to the others.

Answer: C
 Referring to Table 11-3, the value of the test statistic for Levene's test for homogeneity of variances is found in the "Homogeneity of variances" section, where the F ratio is 4.36. The associated p-value is not provided in the table, but it can be calculated using the degrees of freedom and the F ratio. However, the question only asks for the value of the test statistic, which is 4.36. The correct answer is C.
