Answer:
y = -cos(x) -2
Step-by-step explanation:
Multiplying the function value by -1 reflects it across the x-axis. Adding -2 to the function value shifts it down by two units.
reflected: y = -cos(x)
then shifted: y = -cos(x) -2
Answer:
The critical value for the 95% confidence interval is z = 1.96.
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 z = 1.96.
The critical value for the 95% confidence interval is z = 1.96.
Just look at the line and see how many times it goes up it is just like rise over run it is simple
