Accounting Today identified the top accounting firms in 10 geographic regions across the United States. All 10 regions reported growth in 2014 . The Southeast and Gulf Coast regions reported growth of 12.36% and 5.8%, respectively.

Judging from the way the data were collected, which test would likely be most appropriate to employ? Separate-variance t test for the difference between two means Pooled-variance t test for the difference between two means Paired t test F test for the ratio of two variances
