Question

A random sample of 89 eighth grade students' scores on a national mathematics assessment test has a mean score of 282. 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 280. Assume that the population standard deviation is 33. At α = 0.13, 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.
O A. Ho: ≤280
Ha: μ> 280 (claim)
O D. Ho: ≤280 (claim)
Ha: μ > 280
C
O B. Ho: μ = 280
Ha: μ> 280 (claim)
O E. Ho: μ=280 (claim)
Ha: μ> 280
OC. Ho: ≥280 (claim)
Ha: μ < 280
OF. Ho: μ< 280
Ha: μ ≥280 (claim)
