1. Determine the upper-tail critical values of F in each of the following two-tail tests.

a. a = 0.02, n₁
= 10, n₂
= 31

b. a = 0.05, n₁
= 10, n₂
= 31

c. a = 0.01, n₁
= 10, n₂
= 31

2. Determine the upper-tail critical value of F in each of the following one-tail tests.

a. a = 0.05, n₁
= 16, n₂
= 21

b. a = 0.01, n₁
= 16, n₂
= 21

3. The following information is available for two samples selected from independent normally distributed populations.

 Population A: n₁
= 25 S = 25

 Population B: n₂
= 25 S = 9

a. Which sample variance do you place in the numerator of F_STAT?

b. What is the value of F_STAT?
