For each of the cases that follow, identify the rejection region that should be used to test H0: 0'? S 0% against Ha: a? > 0%. Assume that d.f.1 = 9, d.f.2 = 40. a. a = 0.10 b. 0'. = 0.05 c. a = 0.025 d. 0: = 0.01 a. The rejection region is F > D. (Round to the nearest hundredth as needed.) b. The rejection region is F > :|. (Round to the nearest hundredth as needed.) c. The rejection region is F > :|. (Round to the nearest hundredth as needed.) d. The rejection region is F > :|. (Round to the nearest hundredth as needed.)
