Stat 215 Assignment 8 Module: Poisson , Exercise: Traps Objective : (not available) Problem Description : A series of 40 insect traps were set within a region of sand dunes. The number of insects caught over a fixed time per trap for each of two taxa were counted. The mean number of Staphylinoidea was 1.2, whereas the mean number of Hemiptera was 2.1. Assume the insects of the taxa are spread randomly across the dunes, and thus the Poisson distribution is appropriate. The following Poisson Java applet displays the probabilities of a Poisson random variable, initially for Hemiptera . Use this applet to answer the questions below. Question What is the probability that no insects, i.e., P(X = 0), are caught in a trap for Hemiptera? Answer P(X = 0) = 0.1224 for Hemiptera. Your Answer P(X=0) = 0.1224 Grader Comments (none) Grade 1.0 (out of 1.0) Total 10.0 (out of 10.0) Question What is the probability that at least 2 insects, i.e., P(X >= 2), are caught in a trap for Hemiptera?
