A random sample of 88 eighth grade students' scores on a national mathematics assessment test has a mean score of 293. This test result prompts a state schoo administrator to declare that the mean score for the state's eighth graders on this exam is more than 285. Assume that the population standard deviation is 37. At a = 0.08, is there enough evidence to support the administrator's claim? Complete parts (a) through (e). (a) Write the claim mathematically and identify H, and Ha. Choose the correct answer below. O A. Ho: H= 285 Ha:u> 285 (claim) ΟΒ. Hρ μ2 285 (claim) Ha:H<285 Ο . H : μ< 285 Ha:H2 285 (claim) F. Ho: HS285 H:u> 285 (claim) O D. Ho: Hs285 (claim) O E. Ho:H= 285 (claim) Ha: u> 285 Ha: H> 285 (b) Find the standardized test statistic z, and its corresponding area. (Round to two decimal places as needed.)
