question 75

Short Answer

Specify the appropriate rejection region for testing
$\mathrm { H } _ { 0 : } : \sigma _ { 1 } ^ { 2 } = \sigma _ { 2 } ^ { 2 }$ in the given situation.
- $\mathrm { H } _ { \mathrm { a } } : \sigma _ { 1 } ^ { 2 } < \sigma \underset { 2 } { 2 } ; \alpha = 0.01 , \mathrm { n } _ { 1 } = 16 , \mathrm { n } _ { 2 } = 31$
A) F $> 3.21$
B) $F > 2.70$
C) $F > 2.64$
D) $| \mathrm { F } | > 3.21$

• A) F \(> 3.21\)
• B) \(F > 2.70\)
• C) \(F > 2.64\)
• D) \(| \mathrm { F } | > 3.21\)
