3. At a large call center, the time that it takes to service a call (i.e., call duration from pick up to hang up) can be modeled as an Erlang random variable X having expected value 0.25 in units of hours) and variance 0.03125 (in units of hours hours'). A call lasting 0.1 hours or less is considered to be a short call. Determine the conditional pdf of the random variable X given that the call duration is short. Also...
