6.1.3. Consider the set of infinite-by-infinite matrices with real entries that have only finitely many nonzero entries. (Such a matrix has entries aij, where i and j are natural numbers. For each such matrix, there is a natural number n such that aij 0 ifi-n or j 〉 n.) Show that the set of such matrices is a ring without identity element.

The value of the R function "mean" applied to a vector $\mathbf{v}=(v_1,v_2,...v_n)$ is the arithmentic mean of the vector: $\bar{v}=\frac{1}{n} \sum_{i=1}^nv_i$. The value of the R function "var" applied to the vector $\mathbf{v}$ equals $\frac{1}{n-1} \sum_{i=1}^n(v_i-\bar{v})^2$, a measure of how much the values differ from the mean. For $\lambda\in\{4,25,100\}$, create samples of size 100,000 from the Poisson distribution with parameter $\Lambda$ and the Normal distribution with mean equal to $\lambda$ and sd equal to $\sqrt{\Lambda}$. Please compare the values of...
