A random sample of 75 eighth grade students' scores on a national mathematics assessment test has a mean score of 293. 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 285. Assume that the population standard deviation is 32. At a =0.14, is there enough evidence to support the administrator's claim? Complete parts (a) through (e). (a) Write the claim mathematically and identify Ho and H. Choose the correct answer below. OA. H p2 285 (claim) H u<285 OD. H = 285 O B. H: = 285 (daim) H, p> 285 OE Hu<285 H p2 285 (claim) C. H: us 285 H p> 285 (claim) OF. H: us 285 (claim) H> 285 (claim) Hp> 285 (b) Find the standardized test statistic z, and its corresponding area. z= 2.17 (Round to two decimal places as needed.) (c) Find the P-value. P-value= (Round to three decimal places as needed.)

A random sample of 75 eighth grade students' scores on a national mathematics assessment test has a mean score of 293. 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 285. Assume that the population standard deviation is 32. At a = 0.14, is there enough evidence to support the administrator's claim? Complete parts (a) through (e).
(a) Write the claim mathematically and identify Ho and Ha. Choose the correct answer below.
O A. Ho: H2285 (claim)
O B. Ho: H= 285 (claim)
Ha:H> 285
Ψc. H : μ# 285
Ha:H<285
Ha: µ> 285 (claim)
OD. Ho:H= 285
Ο Ε. H : μ< 285
Ha: H2 285 (claim)
O F. Ho:us285 (claim)
H:µ> 285
Hai H> 285 (claim)
(b) Find the standardized test statistic z, and its corresponding area.
z = 2.17 (Round to two decimal places as needed.)
(c) Find the P-value.
P-value =
(Round to three decimal places as needed.)
