In stratified random sampling, Neyman optimal allocation determines the stratum sample size n_h to minimize total estimation variance for a fixed total sample size n. Which formula correctly defines the stratum sample size under Neyman allocation?

n_h = n * [ (N_h * S_h) / Σ (N_k * S_k) ] n_h = n * [ N_h / Σ N_k ] n_h = n * [ S_h^2 / Σ S_k^2 ] n_h = n * [ (N_h / S_h) / Σ (N_k / S_k) ]

Correct Answer:

n_h = n * [ (N_h * S_h) / Σ (N_k * S_k) ]
