Question
The mean and variance of random variables X, Y, and Z are given as follows: ux = 1, ož =
%3D
In addition, we know that random variables X and Z are
Hy = 6, oỷ = 1, and µz = 3, o} :
NOT independent, and that ox+22-5 = 7. Based on the provided information, answer the
following questions:
%3D
a) Find the covariance of X and Z (i.e., oxz).
b) Calculate E(Y²).
c) Find E(2X + Y – Z).
d) Use the Chebyshev's theorem to give a lower bound for P(3 < Y < 9)? The proposed lower
bound should be obviously larger than zero.
