As your testing H0:p=0.79, then you have a two-tailed test.
The p-value at two-tailed test is given by:
Then, you need to check into the standard normal cumulative table to find at which -z you do have a probability of 0.395. Thus:
As you can see in the picture at z=-0.26 you have a P(Z<=-z)=0.3974
And at z=-0.27 you have a P(Z<=-z)=0.3936.
The average of these values is:
Then, you have a probability of 0.395 at a z of:
Then -z=-0.27, thus z=0.27
Answer:
B)
Step-by-step explanation:
To find the function which has vertex at the origin.
Solution:
For a function to have its vertex at origin the function must pass through point (0,0) which means .
We will find for each of the given functions and check if it has vertex at origin.
To find we will plugin
in the function.
A)
Vertex is not at the origin.
B)
[Any number times zero is = zero]
Vertex is at the origin.
C)
Vertex is not at the origin.
D)
Vertex is not at the origin.
