Claim 1 2 0 05 Population statistics 1 14 and 2 15 Sample statistics x 1 87, n 1 410 and x 2 85, n 2 340 Test the claim about the difference between two population means 1 and 2 at the level of significance Assume the samples are random and independent, and the populations are normally distributed If convenient, use technology

Question: Claim: 1 2 ; = 0.05. Population statistics: 1 = 14 and 2 = 15 Sample statistics: x 1

Claim: μ₁ ≠ μ₂; α = 0.05.

Population statistics: σ₁ = 14 and σ₂ = 15

Sample statistics: x̅₁ = 87, n₁ = 410 and x̅₂ = 85, n₂ = 340

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.
