![E 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).
(a) Write the claim mathematically and identify H, and H. Choose the correct answer below.
A. Ho: µ2 260 (claim)
Ha: H<260
B. Ho:µs260 (claim)
Ha:µ> 260
O C. Ho: H<260
H3: H2 260 (claim)
O D. Ho:HS260
H: µ> 260 (claim)
Ο ΕΕ Ho: μ= 260
O E.
O F. Ho: µ=260 (claim)
Ha:H> 260
Ha:µ> 260 (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.)
(d) Decide whether to reject or fail to reject the null hypothesis.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb40d4242-3ac3-4a23-b8cc-f3704c2db427%2F8ce5c5d1-aacf-414e-a5a8-533900ff9e7c%2F50hkdjr_processed.jpeg&w=3840&q=75)
