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 |
