What are the F critical values below for α = 0.05?
a) df = 4, 14:
b) df = 9, 6:
c) df = 5, 15:
Random Variable F ~ F4,14
F critical value for =0.05 is denoted by F0.05;4,14
This implies :- P(FF0.05;4,14) = 0.05 F0.05;4,14 = 3.11225
[ This value is obtained using from the F-distribution table or by using the function =FINV(0.05,4,14) in Excel 07. ]
Random Variable F ~ F9,6
F critical value for =0.05 is denoted by F0.05;9,6
This implies :- P(FF0.05;9,6) = 0.05 F0.05;9,6 = 4.099016
[ This value is obtained using from the F-distribution table or by using the function =FINV(0.05,9,6) in Excel 07. ]
Random Variable F ~ F5,15
F critical value for =0.05 is denoted by F0.05;5,15
This implies :- P(FF0.05;5,15) = 0.05 F0.05;5,15 = 2.901295
[ This value is obtained using from the F-distribution table or by using the function =FINV(0.05,5,15) in Excel 07. ]
