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.

Demonstrate understanding of the Central Limit Theorem, using R, by showing how the distribution of the sample mean changes according to sample size. Consider a Poisson distribution with λ = 1.5. Generate samples of 10,000 means over different numbers of observations (eg give a matrix 1, 2,3...100) rows. For each of these samples of means, compute the mean of the means, the sample standard deviation of the means, and the proportions of means that are more than 1 standard deviation...

We are introduced to the Central Limit Theorem, so you have to explain what makes the Central Limit Theorem so important to statistics? Then we are introduced to Confidence Intervals. I would like you to explain if we can have a confidence interval for a confidence level of 100%?

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 =...
