Reference no: EM1316815

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 follows:

A	B	C	D
1.2	2.5	1.0	0.8
1.1	2.1	1.5	1.3
0.9	1.9	1.1	1.1
0.4	1.6	1.3	0.7

The ANOVA summary (partial results) is as follows:

SUMMARY
Groups	Count	Sum	Average	Variance
A	4	3.6	0.900	0.127
B	4	8.1	2.025	0.142
C	4	4.9	1.225	0.049
D	4	3.9	0.975	0.076
