Q2.
The
Decision
Sciences
Department
is
trying
to
determine
whether
to
rent
a
slow
or
a
fast
copier.
The
department
believes
that
an
employee’s
time
is
worth
$15
per
hour.
The
slow
copier
rents
for
$4
per
hour
and
it
takes
an
employee
an
average
of
10+5f
minutes
to
complete
copying
(exponentially
*distributed).
The
fast
copier
rents
for
$15
per
hour
and
it
takes
an
employee
an
average
of
6+5f
minutes
to
complete
copying.
An
average
of
4
employees
per
hour
need
to
use
the
copying
machine
(interarrival
times
are
exponential).
Which
machine
should
the
department
rent?
Answer
the
same
question
with
the
following
change:
In
the
fast
copier,
Copying
time
does
not
follow
exponential
distribution
and
it
takes
an
employee
an
average
of
6+5f
minutes
to
complete
copying
with
a
the
standard
deviation
of
copying
time
=
2.5
minutes.

correction
