Question: Claim: 1 2 ; = 0.03. Population statistics: 1 = 136 and 2 = 215 Sample statistics: x 1

Claim: μ₁ ≤ μ₂; α = 0.03.

Population statistics: σ₁ = 136 and σ₂ = 215

Sample statistics: x̅₁ = 5004, n₁ = 144 and x̅₂ = 4895, n₂ = 156

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.
