Answer:
The mean of the sampling distribution of p is 0.75 and the standard deviation is 0.0306.
Step-by-step explanation:
Central Limit Theorem:
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean
and standard deviation ![s = \sqrt{\frac{p(1-p)}{n}}](https://tex.z-dn.net/?f=s%20%3D%20%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%7D)
75% of teenagers in North America are pursuing a goal they have set for themselves.
This means that ![p = 0.75](https://tex.z-dn.net/?f=p%20%3D%200.75)
Sample of 200.
This means that
.
What are the mean and standard deviation of the sampling distribution of p?
By the Central Limit Theorem
Mean ![\mu = p = 0.75](https://tex.z-dn.net/?f=%5Cmu%20%3D%20p%20%3D%200.75)
Standard deviation ![s = \sqrt{\frac{0.75*0.25}{200}} = 0.0306](https://tex.z-dn.net/?f=s%20%3D%20%5Csqrt%7B%5Cfrac%7B0.75%2A0.25%7D%7B200%7D%7D%20%3D%200.0306)
The mean of the sampling distribution of p is 0.75 and the standard deviation is 0.0306.
Answer:
answer B
Step-by-step explanation:
hello,
![f(x)=x+1\\g(x)=5x \ \ so\\(fog)(-1)=f(g(-1))=f(-5)=-5+1=-4](https://tex.z-dn.net/?f=f%28x%29%3Dx%2B1%5C%5Cg%28x%29%3D5x%20%5C%20%5C%20so%5C%5C%28fog%29%28-1%29%3Df%28g%28-1%29%29%3Df%28-5%29%3D-5%2B1%3D-4)
so the winner is the answer B
hope this helps

Answer:
x = 5
Step-by-step explanation:
3x - 2 = x + 8
Subtract x from each side
3x-x - 2 = x-x + 8
2x -2 = 8
Add 2 to each side
2x-2+2 = 8+2
2x = 10
Divide each side by 2
2x/2 =10/2
x = 5
