test
a

dog
food
that

added
omega-3
oils
for
healthy,
shiny
coats.

company
selects
two
groups
of
volunteers
who
have
dogs
as
pets.
They
give
each
person
in
both
groups
a
month's
supply
of
dog
food.
Each
bag
|
of
dog
food
is
unlabeled.
One
group
is
given
the
dog
food
with
the
added
omega-3
oils,
and
the
other
group
is
given
a
brand
of
dog
food
without
the
|
added
omega-3
oils.
Both
groups
are
asked
to
feed
their
dogs
the
food
the
company
gave
them
and
report
whether
they
noticed
an
improvement
in
their
dogs'
coats.
Which
statement
is
correct?
A.

volunteers
in
both
groups
and
the
company
are
all
unaware
of
which
group
received
the
dog
food
with
omega-3
oils.
B.

experiment
is
not
blinded
because
the
volunteers
in
both
groups
are
aware
of
which
type
of
dog
food
they
received.

• Stock solution: 1000 mg/L
Target sample concentrations: 50-400 mg/L
• Create a 5-point standard dilution to cover the test
• If each test only needs 10 mL, make plans to make the dilution so you
have 20 mL of each concentration.
