6 Cards in this Set

  • Front
  • Back
H0 for population variances
[(sigma1)^2/(sigma2)^2] = 1
H1 for population variances
[(sigma1)^2/(sigma2)^2] [>,=,<] 1
F-test
[s1^2/sigma1^2]/[s2^2/sigma2^2]
=> [s1^2/s2^2] since [(sigma1)^2/(sigma2)^2] = 1
F_alpha_v1_v2
Alpha is the are to the right
v1 = df of sample 1 = n1-1
v2 = df of sample 2 = n2-1
***Transformation of
F_1-alpha_v1_v2
1/F_alpha_v2_v1
for testing sigma1^2/sigma2^2 != 1
Rejection region:
F<F_1-alpha_v1_v2 or F>F_alpha_v1_v2
