A random sample of 83 eighth grade students' scores on a national mathematics assessment test has a mean score of 272. 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 270. Assume that the population standard deviation is 38. 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 H, and Ha. Choose the correct answer below. Ο Α. Ho: μ2 270 (claim) Ha: H<270 O c. Ho: µ= 270 (claim) Ha:µ> 270 B. Ho: µ= 270 Ha: µ> 270 (claim) Ο D . Ho: μS 270 E. Ho : με 270 (claim) Ο F. Ho: μ < 270 Ha: µ> 270 (claim) Ha: H> 270 Ha: H2 270 (claim) (b) Find the standardized test statistic z, and its corresponding area. (Round to two decimal places as needed.) (c) Find the P-value. P-value = (Round to three decimal places as needed.)
