Answer:
The mean is 0.54 and the standard deviation is 0.05.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a sample proportion p in a sample of size n, the mean of the sampling distribution is p and the standard deviation is .
In this problem:
So
Mean 0.54
Standard deviation .
The mean is 0.54 and the standard deviation is 0.05.
Answer:
y= 1/3x
Step-by-step explanation:
1.Plug the points into the slope formula- m=y2-y1/x2-x1.
So M=3-(-3)/9-(-9)
2.Solve: M=6/18
3.Simplify: M=1/3
4.Input into y=Mx+b
y=1/3x+b
<em>The x and y won't be changed for this equation.</em>
5.Plug in one of the points into the new equation
For (9,3): 3=1/3*9+b so B=0 because 1/3*9=3 which is what we want.
5.5 Or you can do it by solving for b: b=3-(1/3)(9)=0
6. Therefore B=0
7. So the end equation is y=1/3x
The answer 10 because: 4+36/4
Well it'll be 2.50lbs. divided by $1.25=2
