Q5. 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 My(t) = (1 - Bt). Let X1, X 2,...,x , be a random sample of
n
72
size n from an exponential distribution with mean 1/8 and m. g.f. (1 - 01)-°. Let Y = XX,
i=1
and = 2x;. [For p. d.f. s of Gamma and Exponential, see the book or lecture notes).
i=1
(a) Find the m. g.f. My () of Y and state the distribution of Y specifying the parameters.
(b) Find the m. g.f. My(t)of X and state the distribution of X specifying the parameters.
(C) Suppose you have a random sample of size n = 100 from a Gamma (a, b) distribution
with a = 3 and B = 5/3. Use the Central Limit Theorem to find P(4.5 < X <5.5).

Apsychology student wishes to investigate differences in political opinions between business majors and political science majors at her college. she randomly selects 100 students from the 260 business majors and 100 students from the 180 political science majors. does this sampling plan result in a simple random sample? why or why not? no, because each group of 200 students in the sample does not have the same chance of being selected. yes, because each group of 200 students in the sample has the same chance of being selected. no, because each individual student does not have an equal chance of being selected. yes, because each individual student has the same chance of being selected.
