Answer:
C. With 99% confidence, it can be said that the population proportion of adults who believe in UFOs is between the endpoints of the given confidence interval.
Step-by-step explanation:
A confidence interval let us make an inference about a population parameter from a sample statistic. In this case, a sample proportion let us infere aout the population proportion with a certain degree of confidence.
With this confidence interval, we are 99% confident that the polpulation proportion falls within this interval. This means that there is 99% chances of having the population proportion within this interval.
To estimate the population proportion of adults who do not believe in UFO's we should have to construct another confidence interval with the proportion (1-p), but this parameter can not be estimated from the confidence interval for p.
Answer:
No the relation is not a function
Step-by-step explanation:
This is because there are 2 x factors that have the value of 15. (15,8) and (15,2)
in order to make this a function you would have to change the one of the x factor of the 2 ratios:
(15,8) and (15,2)
Answer:
The original award is of $66666.67 and David receives the most money.
Step-by-step explanation:
Let us assume that the total prize money is $x.
Now, Ailin receives $10000 plus 
of what then remains, and David receives $16000 plus 
of what then remains, and finally Rashaad receives $18000.
So,from the conditions given above we can write
![[10000 + \frac{x - 10000}{5}] + [16000 + (x - 10000 - \frac{x - 10000}{5}) \times \frac{1}{4}] + 18000 = x](https://tex.z-dn.net/?f=%5B10000%20%2B%20%5Cfrac%7Bx%20-%2010000%7D%7B5%7D%5D%20%2B%20%5B16000%20%2B%20%28x%20-%2010000%20-%20%5Cfrac%7Bx%20-%2010000%7D%7B5%7D%29%20%5Ctimes%20%5Cfrac%7B1%7D%7B4%7D%5D%20%2B%2018000%20%3D%20x)
⇒ 
⇒ 
⇒ 
⇒ 
⇒ x = $66666.67
Therefore, Ailin receives ![[10000 + \frac{66666.67 - 10000}{5}]](https://tex.z-dn.net/?f=%5B10000%20%2B%20%5Cfrac%7B66666.67%20-%2010000%7D%7B5%7D%5D)
= $21333.34
And David receives ![[16000 + (66666.67 - 10000 - \frac{66666.67 - 10000}{5}) \times \frac{1}{4}]](https://tex.z-dn.net/?f=%5B16000%20%2B%20%2866666.67%20-%2010000%20-%20%5Cfrac%7B66666.67%20-%2010000%7D%7B5%7D%29%20%5Ctimes%20%5Cfrac%7B1%7D%7B4%7D%5D)
= $27333.33
The original award is of $66666.67 and David receives the most money. (Answer)
