Select an Appropriate Null Hypothesis for a One Way Analysis $H _ { 0 } : \mu _ { 1 } = \mu _ { 2 } = \mu _ { 3 } = \mu _ { 4 }$

question 137

Short Answer

Select an appropriate null hypothesis for a one way analysis of variance test.
A) $H _ { 0 } : \mu _ { 1 } = \mu _ { 2 } = \mu _ { 3 } = \mu _ { 4 }$
B) $H _ { 0 } : \mu _ { 1 } \neq \mu _ { 2 } \neq \mu _ { 3 } \neq \mu _ { 4 }$
C) $H _ { 0 } : p _ { 1 } \neq p _ { 2 } \neq p _ { 3 } \neq p _ { 4 }$
D) $H _ { 0 } : \sigma _ { 1 } = \sigma _ { 2 } = \sigma _ { 3 } = \sigma _ { 4 }$

• A) \(H _ { 0 } : \mu _ { 1 } = \mu _ { 2 } = \mu _ { 3 } = \mu _ { 4 }\)
• B) \(H _ { 0 } : \mu _ { 1 } \neq \mu _ { 2 } \neq \mu _ { 3 } \neq \mu _ { 4 }\)
• C) \(H _ { 0 } : p _ { 1 } \neq p _ { 2 } \neq p _ { 3 } \neq p _ { 4 }\)
• D) \(H _ { 0 } : \sigma _ { 1 } = \sigma _ { 2 } = \sigma _ { 3 } = \sigma _ { 4 }\)
