In a Factorial ANOVA, the Null Hypothesis for the Interaction

question 49

Multiple Choice

In a factorial ANOVA, the null hypothesis for the interaction might look like this:

• A)H₀: µᵤppₑᵣ × nₑw = µᵤppₑᵣ × ᵣₑtᵤᵣnᵢng = µmᵢddlₑ × nₑw = µmᵢddlₑ × ᵣₑtᵤᵣnᵢng
• B)H₀: µᵤppₑᵣ × nₑw ≠ µᵤppₑᵣ × ᵣₑtᵤᵣnᵢng ≠ µmᵢddlₑ × nₑw ≠ µmᵢddlₑ × ᵣₑtᵤᵣnᵢng
• C)H₁: ᵤppₑᵣ × nₑw = ᵤppₑᵣ × ᵣₑtᵤᵣnᵢng = mᵢddlₑ × nₑw = mᵢddlₑ × ᵣₑtᵤᵣnᵢng
• D)H₁: ᵤppₑᵣ × nₑw ≠ ᵤppₑᵣ × ᵣₑtᵤᵣnᵢng ≠ mᵢddlₑ × nₑw ≠ mᵢddlₑ × ᵣₑtᵤᵣnᵢng
