Essay

In testing the hypotheses:
H₀: $\mu$ ₁ - $\mu$ ₂ = 0
H_A: $\mu$ ₁ - $\mu$ ₂ > 0,
two random samples from two normal populations produced the following statistics:
n₁ = 51, x₁-bar = 35, s₁ = 28.
n₂ = 40, x₂-bar = 28, s₂ = 10.
Assume that the two population variances are different.
What conclusion can we draw at the 10% significance level?
