For a certain section of a pine forest, the number of diseased trees per acre, y, has a Poisson distribution with mean 2 - 11. The diseased trees are sprayed with an insecticide at a cost of $4 per tree, plus a fixed overhead cost for equipment rental at $40. If C denotes the total spraying cost for a randomly selected acre, find the expected value and standard deviation for in dollars. (Round your answers to three decimal places.) = $ 84 = $ 12649 x Within what interval would you expect to lie in dollars with probability at least 0.757 (Round your answers to the nearest cent.)
