Central limit theorem:

Let X1,X2...Xn be the random sample with and > o . Then the probability distribution of

or for large n

Importance:

When we have large sample with mean and standard deviation, but known probability distribution. Then for large sample size ,we can use central limit theorem as approximation. Once we know the the probability distribution then its easy to analyse data.Therefore it is mostly used for large sample,

This week we’ve introduced the central limit theorem. According to the central limit theorem, for all samples of the same size n with n>30, the sampling distribution of x can be approximated by a normal distribution. In your initial post use your own words to explain what this theorem means. Then provide a quick example to explain how this theorem might apply in real life. At last, please share with us your thoughts about why this theorem is important.

Central limit theorem is important because? For a large , it says the population is approximately normal. For a large , it says the sampling distribution of the sample mean is approximately normal, regardless of the shape of the population. For any population, it says the sampling distribution of the sample mean is approximately normal, regardless of the sample size. For any sized sample, it says the sampling distribution of the sample mean is approximately normal.

This problem involves using R to examine the Central Limit Theorem more in detail. For all answers in this problem, round to four decimal places. We will first generate 10 Poisson(λ=1) random variables and then calculate the sample mean of these 10 random variables. We will do this process 10,000 times to generate 10,000 simulated sample means. Run the following code and use the output to answer the following questions. set.seed(2020) nsims = 10000 # number of simulations means =...
