Answer:
The sampling distribution of sample proportion is approximately normal, with mean 0.62 and standard deviation 0.0485.
Step-by-step explanation:
Central Limit Theorem
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 proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
62% of those people get some relief from taking ibuprofen (true proportion).
This means that
Sample of 100
This means that
A. (4 pts.) Determine the sampling distribution of sample proportion. Also, find the mean and standard deviation of the sampling distribution.
By the Central Limit Theorem, it is approximately normal with
Mean

Answer:
Step-by-step explanation:
1. Federal Debt=18 trillion dollars.
=18,000,000,000,000
2. Population =320 million people.
=320,000,000
3. Federal Debt Per Capita
Debt Per Capita =Debt/Population
Therefore:
Federal Debt Per Capita
