X: number of trees in t acres ~ Poisson((=80t) (a) (=80(1/4)=20 then P(X≤16)=0.221 (b) t=85000 acres then E(X)= (=80(85000)=6.800,000 (c) Area of the circle==0.031416 square miles or 20.106 acres. Thus X~Poisson((=80(20.106)=1608.48) 9. Exercise 3.106 (Exercise 3.104 in the 5th edition) X: number of grasshoppers per square yard ~ Poisson((=2) ................
