4. Let N be a Poisson(λ) random variable. We observe N, say it equals n, we then throw a p-biased coin n times and let X be the number of heads we get. Show that X is a Poisson(pλ) random variable. (You can use the following identity: ∑ ∞ k=0 (y^k)/ k! = e^y .)

Let XiXi for i=1,2,3,…i=1,2,3,… be a random variable whose probability distribution is Poisson with parameter λ=9λ=9. Assume the Xi are independent. Note that Poisson distributions are discrete. Let Sn=X1+⋯+Xn. To use a Normal distribution to approximate P(550≤S64≤600), we use the area from a lower bound of __ to an upper bound of __ under a Normal curve with center (average) at __ and spread (standard deviation) of __ . The estimated probability is __
