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 x̅ 2 = 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.
