There is a set of n pairs of observation. To conduct a signed-rank sum test, the null hypothesis should be stated. Choose the possible correct statement for testing hypotheses. A) H₀: μ_d = μ₁ - μ₂ = 0 B) H₀: μ_d = μ₁ - μ₂ 0 C) H₀: μ_d = μ₁ - μ₂

Question

There is a set of n pairs of observation. To conduct a signed-rank sum test, the null hypothesis should be stated. Choose the possible correct statement for testing hypotheses. A) H₀: μ_d = μ₁ - μ₂ = 0 B) H₀: μ_d = μ₁ - μ₂ > 0 C) H₀: μ_d = μ₁ - μ₂ < 0 D) H₀: μ_d = μ₁ - μ₂ ≠ 0

The null hypothesis for a signed-rank sum test typically states that there is no difference between the pairs of observations, which means the median difference is zero. This is correctly represented in option A, where the difference (μ1 - μ2) is stated to be equal to 0.
