![A random sample of 84 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 33. At α = 0.08, is there enough evidence to support the administrator's claim? Complete parts (a) through (e).
(a) Write the claim mathematically and identify Ho and H₂. Choose the correct answer below.
Ο A. Ho: μ < 260
Ha: μ ≥260 (claim)
D. Ho: μ=260 (claim)
Ha: μ> 260
B. Ho: μ ≥260 (claim)
Ha: μ< 260
E. Ho: μ≤260 (claim)
Ha: μ> 260
O C. Ho: μ = 260
Ha: μ> 260 (claim)
