• A)H0: μ1 = μ2 = μ3 = μ4 vs.the alternative that not all the document mean times are equal
• B)H0: μ1 = μ2 = μ3 = μ4 vs.the alternative that not all the printer mean times are equal
• C)H0: μ1 ≠ μ2 ≠ μ3 ≠ μ4 vs.the alternative that all the printer mean times are equal
• D)H0: μ1 ≠ μ2 ≠ μ3 ≠ μ4 vs.the alternative that all the document mean times are equal
• E)H0: μprint ≠ μdoc vs.the alternative that printer and document mean times are equal
