Find the appropriate critical F-value for each of the following using the F-distribution table, a. D. = 24, D, = 15, a = 0.05 b. D. = 15, D2 = 9, a = 0.05 C. D. = 24, D2 = 15, a = 0.01 a. The critical F-value when D, = 24, D2 = 15, and a = 0.05 is (Round to three decimal places as needed.) b. The critical F-value when D, = 15, D, =9, and a = 0.05 Is (Round to three decimal places as needed.) c. The critical F-value when D, = 24, D, = 15, and a = 0.01 is (Round to three decimal places as needed.)
