customer to enter a retail shop after 9:00 AM is a random
variable Y with an exponential density function given by (see
image).
a. Derive the moment-generating function of
Y.
b. Derive E(Y) and V(Y) using the answer in part
a.
Suppose that the waiting time for the first customer to enter a retail shop after 9:00 A.M. is a random variable Y with an exponential density function given by (0) e-plo y >O, f(y) = f 0, elsewhere.
