Question:

Claim: μ₁ ≤ μ₂; α = 0.05. Assume σ₁² ≠ σ₂².

Sample statistics: x̅₁ = 2410, s₁ = 175, n₁ = 13 and

x̅₂ = 2305, s₂ = 52, n₂ = 10

Test the claim about the difference between two population means μ₁ and μ₂ at the level of significance α. Assume the samples are random and independent, and the populations are normally distributed. If convenient, use technology.
