Claim: 1 2 2 2 ; = 0.05. Sample statistics: s 1 2

Claim: σ₁² ≠ σ₂²; α = 0.05.

Sample statistics: s₁² = 245,

n₁ = 31 and s₂² = 112, n₂ = 28

Test the claim about the difference between two population variances σ₁² and σ₂² at the level of significance a. Assume the samples are random and independent, and the populations are normally distributed. If convenient, use technology
