Question

Determine F Land F U, the lower- and upper-tail critical values of F, in the following two-tailed tests:

alpha = 0.05, n_1=16, n_2= 21

a. F_L = 0.429, F_u = 2.20

b.F_L = 0.362, F_u = 2.57

c. F_L = 0.297, F_u = 3.09

d. F_L = 0.258, F_U = 3.50

Answer 1

F_L = F(0.975, 15, 20) = 0.36

F_R = F(0.025, 15, 20) = 2.57

Option - b) F_L = 0.362, F_R = 2.57
