Arandom sample of 78 eighth grade students' scores on a national mathematics assessment test has a mean score of 284.
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 32. at α=0.04, is there enough evidence to support the administrator's claim. a)
h0: μ≤275ha: μ> 275(claim)
b) find the standarized test statistic z and its corresponding areac) find the p valued) describe whether to reject or fail the null hypothesise) interpret your decision in the context of the original claim
