Question:

(a) Find the critical F-value for a right-tailed test with a = 0.05, degrees of freedom in the numerator = 8, and degrees of freedom in the denominator = 9.

(b) Find the critical F-value for a two-tailed test with a = 0.05, degrees of freedom in the numerator = 10, and degrees of freedom in the denominator = 5.
