Q1.
A continuous r.v. X is said to have a Gamma (a, B) distribution if its moment generating
function (m.g.f.) is given by Mx (t)= (1-)". Let X1,X 2,.X , be a random sample of size n from an
2.....
exponential distribution with mean 1/0 and m.g.f. (1-0t). Let Y = Ex, and X
i=l
(a) Find the m.g.f. My (1) of Y.
(b) State the distribution of Y specifying the parameters.
(c) Find the m.g.f. M7(t) of X.
