The

The
 Right
 to
 Vote
 (and
 not
 to
 wait)
 
 
In
 the
 previous
 two
 presidential
 elections
 in
 the
 United
 States,
 very
 long
 wait
 times
 have
 been
  witnessed
 at
 precincts
 (voting
 stations)
 in
 states
 that
 ultimately
 decided
 the
 election
 (Florida
 in
  2000
 and
 Ohio
 in
 2004).
 
 

 In
 Philadelphia
 as
 well,
 some
 voters
 complained
 about
 the
 long
 lines
 in
 some
 precincts,
 with
  most
 complaints
 coming
 from
 precinct
 A.
 In
 2004,
 the
 average
 number
 of
 voters
 arriving
 at
  Precinct
 A
 was
 35
 per
 hour,
 and
 the
 arrivals
 of
 voters
 were
 random
 with
 inter-­‐arrival
 times
 that
  had
 a
 coefficient
 of
 variation
 of
 1
 (CVa=1).
 

  Philadelphia
 had
 deployed
 1
 voting
 machine
 in
 Precinct
 A.
 Suppose
 that
 each
 voter
 spent
 on
  average
 of
 100
 seconds
 in
 the
 voting
 booth
 (this
 is
 the
 time
 needed
 to
 cast
 her/his
 vote
 using
 a
  voting
 machine),
 with
 a
 standard
 deviation
 of
 120
 seconds.

 How
 long
 on
 average
 did
 a
 voter
 have
 to
 wait
 in
 line
 precinct
 at
 A
 in
 2004
 before
 entering
  in
 a
 booth
 to
 cast
 her/his
 vote?
