Answer.Given that Y∼ poisson (lambda=13). From this E(y)=13 &e V(y)=13 Let c denote the total spraying cost for a randomly selected acre.Also, the diseased tres are sprayed with an insecticide at a cost of $5 per tree, plus a fixed overhead cost for iquipment rental of $ 40This implies c=5y+40Therefie, the excepted valued is computed as follows{:[E(c)=E(5y+40)],[=E(5y)+E[40] ...
