Answer:
E. Approximately normal with standard deviation less than 0.7 sibling
Step-by-step explanation:
To solve this question, we use the Central Limit theorem.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation
, a large sample size can be approximated to a normal distribution with mean
and standard deviation
In this problem, we have that:
Skewed right distribution, with
Sampling distribution of the sample mean for samples of size 100
By the Central Limit Theorem, they will be approximately normal, with mean , and standard deviation
So the correct answer is:
E. Approximately normal with standard deviation less than 0.7 sibling
Answer:
I = 1.47001
Step-by-step explanation:
we have the function
In polar coordinates we have
and dA is given by
Hence, the integral that we have to solve is
This integral can be solved in a convenient program of your choice (it is very difficult to solve in an analytical way, I use Wolfram Alpha on line)
I = 1.47001
Hope this helps!!!
