Question Help A random sample of 89 eighth grade students' scores on a national mathematics assessment test has a mean score of 268. 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 36. At a = 0.07, is there enough evidence to support the administrator's claim? Complete parts (a) through (e). (b) Find the standardized test statistiIc 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.) (d) Decide whether to reject or fail to reject the null hypothesis. O Fail to reject Ho O Reject Ho (e) Interpret your decision in the context of the original claim. enough evidence to the administrator's claim that the mean score for the state's eighth graders on the exam is more At the 7% significance level, there than 260.
