II. The goal of this problem is to simulate the distribution of the sample mean. We will use the buit load the dataset and avoid some problems, copy and paste the following command in dataset 1ynx. To lynx as.numeric(lynx) Assume this vector represents the population. Le, the mean of this vector is our "true mean" (a) Draw a histogram of the population, find the "true" mean, and the true" variance. Does this data look normally distributed?...

R1. Suppose X is a continuous RV with E(X-μ and Var(X-σ2 where both μ and σ are unknown. Note that X may not be a normal distribution. Show that X is an asymptotically unbiased estimator for μ2. (This problem does not require the computer.) R2. Let X ~ N(μ 10.82). Following up on R1, we will be approximating μ2, which we can see should be 100, For now, let the sample size be n 3. Pick 3 random numbers from...

R2 IS THE QUESTION,THANKS!
R2. Let X ~ N(μ = 10.82). Following upon we be approximating μwe can see should be 100. For now, let the sample size be n = 3, Pick 3 random numbers from X, compute X', and repeat the process a total of 50000 times. Plot a smooth version of the histogram of these 50000 values for X: the plot(density(...)) command in R will be useful. Now find the average of your 50000 values and make...
