Answer:
p-value: 1.000
There is enough evidence at the 1% level of significance to suggest that the proportions are not equal.
Step-by-step explanation:
We will be conducting a difference of 2 proportions hypothesis test
The hypothesis for this test is:
H_0: p1 - p2=0
H_a: p1 - p2 ≠0
(p1 ) = 252/300 = 0.84
(p2) = 195/300 = 0.65
This is a 2 tailed test with a significance level of 1%. So our critical values are: z > 2.575 and z < -2.575
See the attached photo for the calculations for this test

<h2>Explanation:</h2>Using graph tools we can graph the function:
which is the red graph shown below. As you can see, this is a parabola. The rule for vertical and horizontal shifts is as follows:
Therefore, If we shift the red graph 9 units to the right and 1 down, our new function (let's call it ) will be:
This graph is the blue graph below. Let's verify the transformation taking the vertex of the red graph:
By translating the 9 units to the right and 1 down the vertex is also translated by the same rule, so:
