Finding the sampling distribution of a Poisson distribution. Using do-loops,
generate 20 samples of size n= 15 from a Poisson Distribution (ranpoi) with
a mean of 3. Use the computer clock as the seed number. Find the mean of
each of your samples. (You don't have to show me this values)
用do-loops生成20组随机数，每组15个数字，并且符合柏松分布，mean=3
另外seed用电脑的时间
试了半天不知道怎么分组？
望解答。。 | H********8
