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...

Problem 3 The time (in years) after reaching age sixty that it takes an individual to retire is approximately exponentially distributed with a mean of about five years. Suppose we randomly pick one retired individual. We are interested in the time after age sixty to retirement. In each appropriate box you are to enter either a rational number in "p/q" format or a decimal value accurate to the nearest 0.01 . a. The time after sixty to retirement is modeled...
