Suppose Z and V are two independent random variables, Z has the normal distributionwith expected value 0 and variance1 and V = 1 or -1, each with probability0.5. Let Y = ZV.
a. Derive the distribution of Y.
b. Find the covariance of Y and Z.
c. Are Y and Z independent? Justify your answer.
Please see the attached file. Hope it helps.
a. This implies that Y follows the standard normal distribution N(0,1) …
The expert examines the intereference in statistics. The covariance of Y and Z are determined.
