hi
I hope you and your family are safe in this pandemic.
I) For the first plot the answer is Uniform on (0,1).
2) For the second plot the answer is Gaussian with variance 10 Ñ (0,10)
3) For the third plot the answer is Exponential with mean 1 EXP (1)
4) For the fourth plot the answer is Standard gaussian Ñ( 0,1).
I hope you get the answers.
All the best.

Generate Figure 4.6 uses the QQ plot by Matlab
Please give me the matlab codes, and capture the generated figures.Fig.4.6. Quantile-quantile plot for samples of the form (4.7) against \(\mathrm{N}(0,1)\) quantiles.Computational example In Figures \(4.5\) and \(4.6\) we use the techniques introduced above to show the remarkable power of the Central Limit Theorem. Here, we generated sets of \(\mathrm{U}(0,1)\) samples \(\left\{\xi_{i}\right\}_{i=1}^{n}\), with \(n=10^{3}\). These were combined to give samples of the form$$ \frac{\sum_{i=1}^{n} \xi_{i}-n \mu}{\sigma \sqrt{n}} $$where \(\mu=\frac{1}{2}\) and \(\sigma^{2}=\frac{1}{12} .\) We repeated this \(M=10^{4}\) times. These \(M\) data...

This question is to help you understand the idea of a sampling dis- tribution. Let Xi, , xn be IID with mean μ and variance σ2. Let Xi. Then Xn is a statistic, that is, a function of the data. Since Xn is a random variable, it has a distribution. This distri- bution is called the sampling distribution of the statistic. Recall from Theorem 3.17 that E(Xn) μ and V(Xn) σ2/n. Don't confuse the distribution of the data fx and...
