Answer:
Skewed Left
Step-by-step explanation:
The shape of the sampling distribution of -x will match the shape of the parent population since the sample size is small (n=4<30, although it will be closer to normal than the parent population is.
Answer: Im pretty sure it is the equal sign with the line between it
pretty sure that is it tho
Hope that helped
Step-by-step explanation:
Answer:
and 
Step-by-step explanation:
To find the max points we need to take the derivative of the function and then find the critical values.
First we take the derivative:

Now we need to find when f'(x)=0 to find the critical values.

The critical values will be
for any integer n
between 0 and 2 pi, the critical values will be

We can determine if these are minimums or maximums by using the second derivative test.
So we need to take the second derivative;

We need to see if the second derivative is positive or negative to determine if it is a max or min.

Since the second derivative is negative at
and 
we know both of those are the x-values of maximums.
Answer: its slope is 0 so false
