At a doctor’s office, patients are called in from the waiting
room according to a Poisson
distribution with an average of 2 patients every 15
minutes.
a) On average, how many patients are called in to see the
doctor between 3:15pm-
4:15pm?
b) On average, how long does it take for a patient to finish
their appointment with the
doctor (seeing the doctor, not including the waiting
time)?
c) You are at the doctor’s office and there are 3 patients in
front of you. The time is
now 2:45pm and the first patient has been called in. At what
time do you expect to
be able to leave the doctor’s office (after finishing your
appointment)?
d) What is the probability that a patient has to wait longer
than 10 minutes to be
called in if he is the next in line to be called in?
