Question: Suppose that (X1, Y1), . . . , (Xn, Yn) form a random sample from a bivariate normal distribution with means x and y, variances

Suppose that (X1, Y1), . . . , (Xn, Yn) form a random sample from a bivariate normal distribution with means μx and μy, variances σ2x and σ2y, and correlation ρ. Let R be the sample correlation. Prove that the distribution of R depends only on ρ, not on μx, μy, σ2x, or σ2y.
