For each of the cases that follow, identify the rejection region that should be used to test Ho: 0? s 0: against Ha: (I? > 0:. Assume that d.f.1 = 7, d.f.2 = 30. a. 0: = 0.10 b. o: = 0.05 c. a = 0.025 d. a = 0.01 a. The rejection region is F > El. (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.)
