In using the Z-test for comparing two proportions,the null hypothesis is typically stated as ____.
A)π₁ = π₂.
B)π₁ ≠π₂.
C)π₁ x π₂ = 1
D)π₁ - π₂= 1

Question

Quizplus · Accepted Answer

The null hypothesis for the Z-test for comparing two proportions is typically stated as π₁ = π₂, meaning that there is no significant difference between two proportions being compared. This is the best choice as it accurately represents the null hypothesis in this scenario. Option B) represents a two-tailed test, which is not specific to the Z-test for comparing two proportions. Option C) represents a multiplication of two proportions, which is not relevant to the null hypothesis. Option D) represents a subtraction of two proportions, which is not the same as the null hypothesis for the Z-test for comparing two proportions.
