PLEASE USE R CODE!!
Continue to generate standard normal random variables until you have generated n of them, where n≥100 is such that S/sqrt(n) <0.1, where S is the sample standard deviation of the n data value.
(a)How many normals do you think will be generated?
(b)What is the sample mean of all the normals generated?
(c)What is the sample variance?

R Programming Exercise Book Problem 57 (Difficulty: Easy) A normal distribution has a standard deviation of 35 and mean of 15. From this generate 2 to 400 samples. After generating the samples utilize the plot command to plot the mean of the generated sample (x-axis) against the number of samples. Create a second plot of the density of the 400 samples that you generated. This code can be solved in 4 to 8 lines. For this problem use the following...

Conduct a computer simulation to generate the sample means of Poisson random variables. First generate X ∼ Poisson(3), and plot a histogram of this Poisson random variable. Then generate X = 1/5(X1 + X2 + X3 + X4 + X5), where X1, X2, . . . , X5 are all from Poisson(3). Plot a histogram of this sample mean statistic X. Compare the histograms and describe the changes you see in the histograms. Explain the changes using Central Limit Theorem....

Suppose that X is a standard normal random variable with mean 0 and variance 1 and that we know how to generate X. Explain how you would generate Y from a normal density with mean μ and variance σ"? That is, given that we already generated a random variate X from N(0,1), how would you convert X into Y so that Y follows N (μ, σ 2)?
