Claim 1 2 0 05 Population statistics 1 75 and 2 105 Sample statistics x 1 2435, n 1 35 and x 2 2432, n 2 90 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 = 75 and 2 = 105 Sample statistics: x 1

Claim: µ₁ < µ₂; α = 0.05

Population statistics: σ₁ = 75 and σ₂ = 105

Sample statistics: x̅₁ = 2435, n₁ = 35 and x₂ = 2432, n₂ = 90

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.
