question 28

Short Answer

AAA Co. operates distribution centers in the Midwest. Three of their centers were recently audited to determine if they are in compliance with company standard billing procedures.

Center 1: 385 billings
Center 2: 305 billings
Center 3: 210 billings
What is the critical value at α = .01 to test the null hypothesis (equal billings from each center)?
