A country's Department of Health wants to estimate average hospital beds per state using two approaches:
Design 1 (Simple Random Sampling): Randomly select 200 hospitals nationwide and count beds.
Design 2 (Two-Stage Cluster Sampling): Stage 1 — Randomly select 10 of the 50 states. Stage 2 — Within each selected state, randomly select 20 hospitals and count beds.
