Answer:
"If we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be more than 36%?"
Step-by-step explanation:
The third option. When running the hypothesis test, you are comparing your sample size (of the campus) to the known sample size (the results given by the Pew Research Center). The results of the test give you the probability of the sample happening by random chance. We always test for equality (the sample being equal to the population), so if we reject the null, there will be evidence to suggest that the population proportion is actually more, given that the sample is an unbiased representation of the actual population
1) Write the equation (27=x(4+5)).
2) Simplify (27=9x).
3) Divide by 9 (x=3).
4) Multiply by 5 (3×5=15).
The answer is there are 15 girls in Liza's classroom.
First we distribute
![\frac{1}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7D%20)
into
![n](https://tex.z-dn.net/?f=n)
and
![-\frac{1}{7}](https://tex.z-dn.net/?f=%20-%5Cfrac%7B1%7D%7B7%7D)
.
![\frac{1}{5} * n = \frac{1}{5} n](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7D%20%2A%20n%20%3D%20%20%5Cfrac%7B1%7D%7B5%7D%20n%20)
![\frac{1}{5} * -\frac{1}{7} = - \frac{1}{35}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7D%20%20%2A%20%20-%5Cfrac%7B1%7D%7B7%7D%20%20%3D%20-%20%5Cfrac%7B1%7D%7B35%7D%20)
That makes the left side of the equation
![\frac{1}{5} n - \frac{1}{35} = \frac{1}{6} n](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7D%20n%20-%20%20%5Cfrac%7B1%7D%7B35%7D%20%3D%20%20%5Cfrac%7B1%7D%7B6%7D%20n)
Now we subtract
![\frac{1}{5}n](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7Dn)
from
![\frac{1}{6} n](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B6%7D%20n)
, which makes
![\frac{1}{30}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B30%7D%20)
Now the equation is
![-\frac{1}{35} = -\frac{1}{30n}](https://tex.z-dn.net/?f=%20-%5Cfrac%7B1%7D%7B35%7D%20%3D%20%20-%5Cfrac%7B1%7D%7B30n%7D%20)
Our goal is to isolate
![n](https://tex.z-dn.net/?f=n)
, so we both sides by 30
That will make the equation
![- \frac{30}{35} = -n](https://tex.z-dn.net/?f=-%20%5Cfrac%7B30%7D%7B35%7D%20%3D%20-n)
We multiply -1 on both sides of the equation:
![\frac{30}{35} = n](https://tex.z-dn.net/?f=%20%5Cfrac%7B30%7D%7B35%7D%20%3D%20n)
Finally we simplify
![\frac{30}{35}](https://tex.z-dn.net/?f=%20%5Cfrac%7B30%7D%7B35%7D%20)
, which makes
So the answer is
Answer:
If a person drink soda, the person will likely answer the question of the survey and SOME PEOPLE MIGHT NOT BE ONLINE TO PARTICIPATE IN THE SURVEY, YET THEY DRINK SODA DAILY.
Step-by-step explanation:
From the question above we are given that the survey of 2028 responses was conducted on the internet through AOL. In the response to the question, " How often do you drink soda?" Only 33% said they drink soda almost every day.
The following should be noted down;
(1). This survey is questionable, (2). This survey is not representative and (3). It is a voluntary response sample.
Because of the third point above, it can be said that the survey response is not representative.
SOME PEOPLE MIGHT NOT BE ONLINE TO PARTICIPATE IN THE SURVEY, YET THEY DRINK SODA DAILY.
