Concept Question 4 Recall the properties of the binomial and Poisson distributions. Part 1 of 3 An assembly line will be shut down if there are two or more defectives found in a random sample of 250 parts. Based on past production, the defective rate is 0.4%%. What is the probability that the assembly line will be shut down based on this sampling plan? (Round your answers to three decimal places.) (1) Solve using the binomial distribution formula. (il) Solve using the Poisson distribution formula, If allowed. (ill) What is the difference in the probabilities
