the slope is -1/2
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.
I’m not if it’s right but I got -4^3 times y^2
