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:
![p = \frac{54}{100} = 0.54](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7B54%7D%7B100%7D%20%3D%200.54)
So
Mean 0.54
Standard deviation
.
The mean is 0.54 and the standard deviation is 0.05.
Take your original equation ![\frac{x}{y} +\frac{y}{x} =-1](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7By%7D%20%2B%5Cfrac%7By%7D%7Bx%7D%20%3D-1%20)
and multiply both sides by
to remove the fractions. You are left with
![x^2+y^2=-xy](https://tex.z-dn.net/?f=%20x%5E2%2By%5E2%3D-xy%20)
So, ![x^2+y^2=-xy](https://tex.z-dn.net/?f=%20x%5E2%2By%5E2%3D-xy%20)
