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

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

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

Option - b) FL = 0.362, FR = 2.57

When performing a hypothesis test for the ratio of two population variances, the upper critical F value is denoted FR. The lower critical F value, FL, can be found as follows: interchange the degrees of freedom, and then take the reciprocal of the resulting F value found in table A-5. FR can be denoted Fα/2 and FL can be denoted F1-α/2 . Find the critical values FL and FR for a two-tailed hypothesis test based on the following values: n1...
