Let N , X1, X2, . . . be independent random variables such that N ∈ Po(λ) and Xk ∈ Po(µ), k = 1, 2, . . . . Determine the limit distribution of Y = X1 + X2 + · · · + XN as λ → ∞ and µ → 0 such that λ · µ → γ > 0. (The sum is zero for N = 0.)
You then sort by random numbers in ascending order. Finally, you take the first 50 sorted employees as your sample. Does this approach constitute a statistical or a nonstatistical sample?
