Find and sketch the density functions of W = X + Y if X and Y are statistically independent.Example: The Gamma Distribution Suppose X ~ T(a, B), then M(t) = dx BaT(a) 22 Now we do a little high school algebra. Define & = Then one may write 1-Bt" Equation (22) as: M(t) = ()ª / (23) dx One recognizes the integrand of Equation (23) as a r(a, 6) density, hence 8. M(t) = (Gr"(1) = (1 - AY• (24) (1 – Bt)a Exercise 5. Verify the algebra leading from Equation (22) to Equation (23).
- (b) (i) Briefly explain how moment generating function of a random variable, y may be used to Generate its moments. (ii) Let the random variable, y have probability density function S(t) = kye-1/2y y20 , elsewhere Where k> 0 is a constant. Find the moment generating function of y and use it to evaluate the mean and variance of y leaving your results in terms of k.While taking a walk along the road where you live, you accidentally drop your glove, but you don't know where. The probability density p(x) for having dropped the glove a kilometers from home (along the road) is -4x p(x) = 4e for x > 0 a. What is the probability that you dropped it within 1 kilometer of home? b. At what distance y from home is the probability that you dropped it within y km of home equal to 0.95? kmBe X a random variable with density function defined by f(x) = -2², , x>0. 3 Get the moment-generating function and based on it, calculate the average and variance of X.
