5 questions. first question: 5.27 The joint pdf of X, Y and Z is f(x,y,z)=4xy^2/9 where 0＜x＜1， 0＜y＜1 and 0＜z＜3 (a) obtain the joint pdf of Y and Z.

- AMS570 Order Statistics 1. Definition: Order Statistics of a sample. Let X 1, X Therefore the pdf of Z (non-zero portion) is: random sample of size n = 4 from a distribution with pdf f(x) = 2x, 0 < x < 1, zero elsewhere. (a) Find the joint pdf of Y 3 and Y 4. (b) Find the conditional pdf of Y 3, given Y 4 = y 4. (c) Evaluate E[Y 3y 4]. Solution: (a)
- To calculate the pdf , we first note that for any fixed number z, the region of the plane where Z
