Answer:
A) reflection across the y-axis
Step-by-step explanation:
If
, then this says that two
-coordinates are equal for opposite values of
.
Let
a point on
.
Then
.
We also know that
and therefore
is also a point on the graph.
If you graph [/tex](-a,b)[/tex] and
you will see they are symmetrical to each about the
-axis.
Example if given both
and
, then
. This means both (2,3) and (-2,3) are points on the graph.
Here is what those two points look like on a Cartesian Plane (please see graph in picture).
Answer:
1.165.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
. So


So the correct answer is:
1.165.
