A random sample of 83 eighth grade students' scores on a national mathematics assessment test has a mean score of 277. This test result prompts state school administrator to declare that the mean score for the state's eighth graders on this exam is more than 270. Assume that the population standard deviation is 39. At x = 0.03, is there enough evidence to support the administrator's claim? Complete parts (a) through (e). (a) Write the claim mathematically and identify Ho and Ha. Choose the correct answer below. OA. Ho: H=270 (claim) H₂: H>270 O D. Ho: H=270 Ha: >270 (claim) OB. Ho: ≥270 (claim) Ha: μ<270 O E. Ho: μ≤270 Ha: H>270 (claim) OC. Ho: <270 Ha: μ ≥ 270 (claim) OF. Ho: Hs 270 (claim) Ha: μ> 270
