3. Let X₁, X2, Xn represent a random sample from a Rayleigh distribution with proba- bility density function given below. X f(x) == ex²/(20), x>0 е (a) Show that E(X²) = 20. Look up 1²-¹e-¹ dt. (b) Find E (1X) and hence find an unbiased estimator of 0. (c) Estimate from the following observations using the estimator found in part (b). the gamma function, I'(z) = 16.88 10.23 4.59 6.66 13.68 14.23 19.87 9.40 6.51 10.95
