The quality control manager of Marilyn's Cookies is inspecting a batch of chocolate chip cookies. When the production process is in control, the average number of chocolate chip parts per cookie is 6.0. The manager is interested in analyzing the probability that any particular cookie being inspected has fewer than 5.0 chip parts. What type of probability distribution will most likely be used to analyze the number of chocolate chip parts per cookie in the following problem? a) Binomial distribution. b) Poisson distribution. c) d) Continuous distribution. None of the above.

Explanation / Answer
