Determine the upper-tail critical values of F in each of the following two-tail tests. a. a = 0.10, n = 31, n = 11 b. a=0.02, n, 31, n = 11 c. = 0.05, n = 31, n = 11 a. The critical value of F when a = 0.10, n = 31, n = 11 is (Round to two decimal places as needed.) b. The critical value of F when a = 0.02, n = 31, n = 11 is (Round to two decimal places as needed.) c. The critical value of F when = 0.05, n, = 31, n = 11 is (Round to two decimal places as needed.)
