Question

Use the Poisson model to approximate the probability. Round your answer to four decimal places. 13) The rate of defects among CD players of a certain brand is 1.4%. Use the Poisson approximation to the binomial distribution to find the probability that among 160 such CD players.received by a store, there is at most one defective CD player. A) 0.8935 B) 0.6551 C) 0.7615 D) 0.3449 E) 0.2385

Answer 1

rol The solution for the problem using binomial distribution given: p=1.4.). (ov) 0.014 Sample size (n) = 160 poissim distribution mean is a mean = >- np => 160 X 0.014 Xanp = 2.24 p(x) = ex using poissim distribution p(x) = el copie a! given there is a atroust one defective iex=1 pel = é a.ak (2.au p(1) = 0.1064 X2:24 [peus 0.23807 from the option, option (6) 0.23857 & is the correct nwy
