Suppose that H 0 : X = Y is being tested against H 1 :

Question:

Suppose that H₀: μ_X = μ_Y is being tested against H₁: μ_X ≠ μ_Y, where σ²_X and σ²_Y are known to be 17.6 and 22.9, respectively. If n =10, m =20, x̅ = 81.6, and y̅ = 79.9, what P-value would be associated with the observed Z ratio?
