Question 9

Short Answer

Specify the appropriate rejection region for testing
H0::σ12=σ22\mathrm { H } _ { 0 : } : \sigma _ { 1 } ^ { 2 } = \sigma _ { 2 } ^ { 2 } in the given situation.
- Ha:σ12>σ22;α=0.01,n1=10,n2=21\mathrm { H } _ { \mathrm { a } } : \sigma _ { 1 } ^ { 2 } > \sigma _ { 2 } ^ { 2 } ; \alpha = 0.01 , \mathrm { n } _ { 1 } = 10 , \mathrm { n } _ { 2 } = 21
A) F>3.46\mathrm { F } > 3.46
B) F>4.81\mathrm { F } > 4.81
C) F>2.84\mathrm { F } > 2.84
D) F>3.46| \mathrm { F } | > 3.46
