For a certain section of a pine forest. there are on average 9 diseased trees per acre. Assume the number of diseased trees per acre has a Poison distribution. The diseased trees are sprayed with an insecticide at a cost of $3 per tree, plus a fixed overhead cost for equipment rental of $50. Let C denote the total spraying cost for a randomly selected acre.
(a) Find the expected value of C.
(b)find standard deviation for C.
(c) Using Chebyshev's inequality, find an interval where we would expect C to lie with probability at least 0.75.
