The
data
in
the
table
represent
the
number
of
licensed
drivers
in
various
age
groups
and
the
number
of
fatal
accidents
within
the
age
group
by
gender.

What
is
the
correct
interpretation
of
the
slope
of
the
least-squares
regression
line for
females?
Select

correct
choice

If
the
number
of
female
licensed
drivers
increases
by
1
(thousand),
then
the
number
of
fatal
crashes
increases
by
0.105
,
on
average.
(Round
to
three
decimal
places
as
needed.)
If
the
number
of
fatal
crashes
increases
by
1,
then
the
number
of
female
licensed
drivers
increases
by
thousand,
on
average.
(Round
to
three
decimal
places
as
needed.)
If
the
average
age
of
all
female
licensed
drivers
increases
by
1,
then
the
number
of
fatal
crashes
increases
by
,
on
average.
(Round
to
three
decimal
places
as

It
does
not
make
sense
to
interpret
the
slope.
The
slope
of
the
regression
line for
males
is
greater
than
that
for
females.
This
means
that
males
tend
to
be
involved
in
more
fatal
crashes
than
females.
An
insurance
company
may
use
this
information
to
argue
for
higher
rates
for
male
customers.
(c)
Was
the
number
of
fatal
accidents
for
16
to
20
year
old
males
above
or
below
average?
Was
the
number
of
fatal
accidents
for
21
to
24
year
old
males
above
or
below
average?
Was
the
number
of
fatal
accidents
for
males
greater
than
74
years
old
above
or
below
average?
How
might
an
insurance
company
use
this
information?
Does
the
same
relationship
hold
for
females?
The
number
of
fatal
accidents
for
16
to
20
year
old
males
was
above
average.
The
number
of
fatal
accidents
for
21
to
24
year
old
males
was
above
average.
The
number
of
fatal
accidents
for
males
greater
than
74
years
old
was
below
average.
An
insurance
company
could
use
it
to
argue
for
higher
rates
for
younger
drivers
and
lower
rates
for
older
drivers.
