Plain-text version
To test H₀: μ = μ₀, when both μ and σ are unknown, the relevant test statistic is: (A) tₙ₋₁ = (x̄-μ₀)/(s/√n) (B) tₙ₋₁ = (x̄-μ₀)/(s/√(n-1)) (C) tₙ₋₁ = (x̄-μ₀)/(σ/√n) (D) tₙ₋₁ = (x̄-μ₀)/(s/n)
Also written as: To test H_0: mu = mu_0, when both mu and sigma are unknown, the relevant test statistic is:
