Chapter 9.5, Problem 6E

Using Table H, find the critical value for each.

a. Sample 1: $s_1^2$ = 27.3, n₁ = 5

Sample 2: $s_1^2$ = 38.6, n₂ = 9

Two-tailed α = 0.01

b. Sample 1: $s_1^2$ = 164, n₁ = 21

Sample 2: $s_1^2$ = 53, n₂ = 17

Right-tailed α = 0.10

c. Sample 1: = 92.8, n₁ = 11

Sample 2: = 43.6, n₂ = 11

Right-tailed α = 0.05
