Determine the upper-tail critical values of F in each of the following two-tail tests. a. a = 0.01, n = 31, n2 = 16 b. a = 0.05, n = 31, n2 = 16 c. a = 0.02, n1 = 31, n2 = 16 a. The critical value of F when a = 0.01, n = 31, n2 = 16 is (Round to two decimal places as needed.) b. The critical value of F when a = 0.05, n = 31, n2 = 16 is (Round to two decimal places as needed.) c. The critical value of F when a = 0.02, ny = 31, ng = 16 is (Round to two decimal places as needed.)
