Question: Claim: p 1 = p 2 ; = 0.05. Sample statistics: x 1 = 425, n 1 = 840 and x 2 = 410,

Claim: p₁ = p₂; α = 0.05.

Sample statistics: x₁ = 425, n₁ = 840 and x₂ = 410, n₂ = 760

Determine whether a normal sampling distribution can be used. If it can be used, test the claim about the difference between two population proportions p₁ and p₂ at the level of significance α. Assume the samples are random and independent.
