When testing H₀: μ₁ − μ₂ = 2, H_A: μ₁ − μ₂ > 2, where ₁ = 522, ₂ = 516, σ₁² = 28,
σ₂² = 24, n₁ = 40, n₂ = 30, at α = .01, what is the test statistic? (Assume unequal variances.)

Question

When testing H₀: μ₁ − μ₂ = 2, H_A: μ₁ − μ₂ > 2, where When testing H0: μ1 − μ2 = 2, HA: μ1 − μ2 > 2, where 1 = 522, 2 = 516, σ12 = 28, σ22 = 24, n1 = 40, n2 = 30, at α = .01, what is the test statistic? (Assume unequal variances.)

When testing H<sub>0</sub>: μ<sub>1</sub> − μ<sub>2</sub> = 2, H<sub>A</sub>: μ<sub>1</sub> − μ<sub>2</sub> > 2, where <sub>1</sub> = 522, <sub>2</sub> = 516, σ<sub>1</sub><sup>2</sup> = 28, σ<sub>2</sub><sup>2</sup> = 24, n<sub>1</sub> = 40, n<sub>2</sub> = 30, at α = .01, what is the test statistic? (Assume unequal variances.)

₁ = 522,

₂ = 516, σ₁² = 28,
σ₂² = 24, n₁ = 40, n₂ = 30, at α = .01, what is the test statistic? (Assume unequal variances.)
