Determine the upper-tail critical values of F in each of the following two-tail tests. a. a = 0.02, n, = 10, n, = 31 b. a = 0.05, n, = 10, n2 = 31 c. a = 0.10, n, = 10, n, = 31 ... . . a. The critical value of F when a = 0.02, n, = 10, n, = 31 is (Round to two decimal places as needed.) b. The critical value of F when a = 0.05, n, = 10, n, = 31 is (Round to two decimal places as needed.) c. The critical value of F when a = 0.10, n, = 10, n2 = 31 is (Round to two decimal places as needed.)
