A random sample of 83 eighth grade students' scores on a national mathematics assessment test has a mean score of 263. This test result prompts a state school administrator to declare that the mean score for the state's eighth graders on this exam is more than 260. Assume that the population standard deviation is 31. At a = 0.04, 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: 2260 (claim) H₂H<260 OD. Ho: 260 = Ha: H>260 (claim) B. Ho: < 260 Ha: 2260 (claim) OE. Ho: $260 Ha: H>260 (claim) OC. Ho: H=260 (claim) H₂:μ>260 OF. Ho: ≤260 (claim) H₂H>260
