Answer:
We want to verify if the true proportion of the alumni provide monetary contributions is higher than 0.15 (Alternative hypothesis), the system of hypothesis are.:
Null hypothesis:
Alternative hypothesis:
And the best answer for this case would be:
Ha: p > 0.15
Step-by-step explanation:
Information given
n=250 represent the random sample taken
X=40 represent the number of people on the alumni mailing list
estimated proportion of people on the alumni mailing list
is the value to verify
z would represent the statistic
represent the p value
Hypothesis to test

Answer:
D
Step-by-step explanation:
We simply simplify and add the like terms in the problem given:
![(x^2-6x^4+4x^3-2x)+(4x-5x^2+4x^3-6x^4)\\=x^2-6x^4+4x^3-2x+4x-5x^2+4x^3-6x^4\\=-12x^4+8x^3-4x^2+2x](https://tex.z-dn.net/?f=%28x%5E2-6x%5E4%2B4x%5E3-2x%29%2B%284x-5x%5E2%2B4x%5E3-6x%5E4%29%5C%5C%3Dx%5E2-6x%5E4%2B4x%5E3-2x%2B4x-5x%5E2%2B4x%5E3-6x%5E4%5C%5C%3D-12x%5E4%2B8x%5E3-4x%5E2%2B2x)
<em>Here, we added the x^4 terms, the x^3 terms, the x^2 terms, and the x terms to arrive at our answer.</em>

<em>Looking at the choices, D matches ours, so D is the correct answer.</em>
