Summary data for two independent samples are p1nbsp 031

Question

1. Summary data for two independent samples are p₁ = 0.36, n₁ = 150, and p₂ = 0.29, n₂ = 100. Use the 0.025 level of significance in testing H₀: π₁ ≤ π₂ versus H₁: π₁ > π₂.

2. Summary data for two independent samples are p₁ = 0.31, n₁ = 400, and p₂ = 0.38, n₂ = 500. Use the 0.05 level of significance in testing H₀: π₁ = π₂ versus H₁: π₁ ≠ π₂.
