Compute the measurement signal-to-noise ratio—that is, |μ|/σ, where μ = E[X] and σ2 = Var(X)—of the following random variables:
(a) Poisson with mean λ;
(b) Binomial with parameters n and p;
(c) Geometric with mean 1/p;
(d) Uniform over (a, b);
(e) Exponential with mean 1/λ;
(f) Normal with parameters μ, σ2.
