A random sample of 66 eighth grade students' scores on a national mathematics assessment test has a mean score of 283. 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 275. Assume that the population standard deviation is 40. At a= 0.11, is there enough evidence to support the administrator's claim? Complete parts (a) through (e). (8) Write the claim mathematically and identify H0 and HE. Choose the correct answer belcw.
