Question: Suppose that U1 has the noncentral t distribution with m degrees of freedom and noncentrality parameter , and suppose that U2 has the noncentral t

Suppose that U1 has the noncentral t with m degrees of freedom and noncentrality parameter ψ, and suppose that U2 has the noncentral t with m degrees of freedom and noncentrality parameter −ψ. Prove that Pr(U1 ≥ c) = Pr(U2 ≤−c).
